BRAAP

Cygnus summed it up best. The closest thing to a cross flow L-series that I can think of, (well the easiest route anyhow), is to utilize and entire Nissan RB series engine. The OS Giken heads are cool, but try finding one. HybridZ member 1 fast z has built his own using some 4 cylinder cross flow heads, (he is a very gifted fabricator). An endeavor not for the faint of heart, definitely an achievement to be proud of for sure. Good luck on your project, Paul Oh, and I found the keys, finally. This thread remained true and informative, open it will remain..

Interesting. In reading the description there are a couple contradictions and other info that just is odd. I don’t want to bash on this gentleman’s nice appearing car, the "basic" exterior and the dash look great, but I’m not seeing anywhere near a $25,000 car here. 1) At the top, the tranny is listed as an Automatic, in the description at the end he says the tranny is a Datsun 4 speed. Picture of the interior looks to be a manual trans… Ok... 2) Small Block Chevy with a Datsun tranny. For a car of this caliber, in my opinion it would make more sense, on a few levels, and be easier to just use a Chevy transmission, manual or auto. 3) Moroso Lightweight Aluminum headers? I didn’t know Moroso sold aluminum headers? I think the owner is mistaking his aluminum Moroso Valve covers for headers?... 4) The engine bay pic doesn’t show very much, but what I do see is a “bubba” upper radiator hose and what else is visible looks just “ho hum”. So what other corners were cut during the V-8 conversion that we can't see? 5) The hood alignment is pretty far out, especially for a $25,000 car. 6) A 350 V-8 in a Z car with a 2 bbl carb? Ok, that’s feasible, but why bother with a V-8 conversion in the first place if you are going to use a 2bbl? With the contradictions in the description, I get the impression the owner is not mechanically inclined and did not do this himself, let alone even know what he has. So why would he try and BS his way through a description of the car if he really hasn’t a clue to the parts in and on the car? Red flag waving saying “who really knows what else might be or might not be in or on this car?” Granted the body work is extensive, but there are too many indicators of corners being cut and contradictions in the description. I’ve seen nicer GTO V-8 converted Z cars sell in the past for much less and the parts used in those conversions were a far better compliment to each other as a package. This car, by its written description, is quite a cobbled mess, the pics aren’t very detailed, but what does show is ho hum craftsmanship at best. Sorry if that offends, but that is my honest $.02

Also of note, the oil pressure, water temp, and fuel gauges in these cars are VERY slow to react and register big changes. In short, the rattling you hear upon initial start up is low oil pressure, as soon as the noise stops, the oil pressure is up, (adequate oil pressure is what caused the noises to go away), even though the gauge is very slow to register that pressure, hence its slow moving up. I’ll spare you my opinion of the OE oil pressure gauge, suffice to say, your ear is a much better and faster indicator, (sound is "real time" indicating) of when you have lost oil pressure. If that happens, the gauge is still registering pressure even though the engine is already seized, Ok, I lied. I gave you my opinion on the OE oil gauge..

Do you own a shop manual for your car? All of your posts thus far have been maintenance related and come across as if you don’t own a manual for your car. Oil on the car has nothing to do with valve stem seals. Worn tired valve stem seals cause the engine burn oil, i.e. smoke. Typical for these cars with their age to have hard valve stem seals, and yes, they can be changed without removing the head. Valve cover gasket leaking is a common cause for a messy oily engine.

Very cool. Nice equipment you have there.. I added the 10 shot rotary magazine option to my S-200-B, and with the bolt action, allows for rapid follow up shots. Just flick the bolt… shoot, flick the bolt… shoot…, just like a bolt action powder burner rifle. I keep another 3 magazines full and ready for quick changing. Though once those 40 shots are done, it is time to pump up the air chamber and reload the magazines which is not so quick. I think one of the high end air gun manufactures offers a semi auto pellet gun for those who prefer to spray. Another benefit of this a particular model is the report. Barely louder than a mouse fart. The trigger mechanism is louder than the report so it doesn’t “alert” the other prey in a crowded area allowing for a few follow up shots before they rest of the survivors figure out what is going on. Nice for starlings as they startle easily. EEwww.. Negative captain. We just round them up and toss them in garbage... Here is another nights take…

Happy Birthday to Ron Tyler. Apparently he adjusted his birth date when he registered.. Hmm.. Probably to mask his real age… FWIW, he turns 41 today! .

When a question or idea is posted that either contains, or can turn into the sharing of information, ideas, concepts, that are new and radical, fresh, hot, etc, the thread will be left alone and allowed to run its course. With our years of being members here on HybridZ, (most of the admins have been here since the forum started), we do our best in discerning whether or not a particular thread does have, or has the potential to offer any value, whether it expands on existing ideas and concepts, or is new in uncharted territory or not, and that it follows within the HybridZ mission statement, which I’m sure every member has read, along with the rules and guidelines. What gets tossed in the shed are the redundant, “will the stock diff hold up to a V-8?", or “help me, my wipers quit working, what to look for?” type questions and those will continue to get thrown in the shed. As has been stated in many other tossed threads, we are not going to spoon feed people information because they don’t want to take the time to spend a few minutes to a few hours searching and researching the information that the rest of us spent months and years “doing” and subsequently writing about here on these pages for others to learn from and expand on for free. This is a forum dedicated to extreme performance Z cars, not so much how to diagnose/maintain/restore a 240 to OE specs. There are other forums for that. Yes, there are more and more new posts being tossed in the shed. The reason is that HybridZ is now plugged “directly” into the Google search engine, (our sponsor, i.e. the ads we now see), and now when any Joe Blow car guy asks Google about something related to "V-8’s", "RB26", "700R4", "water temp sensor", etc, Hybridz will show up in their WWW searches. As such, we have been experiencing an influx of newbies, some that don’t even own Z cars, others that think this is a Camaro Z-28 or iroc-Z forum. One guy thought it was a V-8 Jeep forum! My point is, with a heavier influx of incoming traffic, you are going to see more posts being tossed and due to where these newbies are coming from, a higher percentage of the newbies are going to be asked to search. Now if we did allow all those redundant questions to go on without cleaning house, just how many MORE useless posts do you think the rest of us, that are willing to search, would have to sift through to get the information we are looking for? People complain about bout how much useless info is in their search queries now! Just think how much more crap you’d have to sift through if we didn’t run such a tight ship? ... and other IM style typing in Tony C’s posts… As was politely stated please refrain from IM posting as spelled out in #5 of the guidelines. Thank you. Yeup, but only for those too lazy to use the search feature before they post simple common questions. I agree. Some of the titles are ridiculous and by title alone probably should be tossed in the shed, especially being as we are asked in the rules and guidelines #3, to post a topic title that is relevant to the thread. Well, due to the fact that some of those badly titled threads have some good info or are relevant HybridZ questions, or some are just entertaining and posted in the non tech forum where they belong, those threads are left alone. As was pointed out a few posts up, the advanced search feature allows custom searching for narrowing down specific searches. Also, the search feature by default, searches entire threads, not just the title, unless you tell it to look at just the titles only. Due to the problem of non specific thread titles, I don’t recommend allowing the search engine to read "titles only" in your searches. To sum up. HybridZ is what it is, and will remain THE Z car tech resource for all things extreme performance related. Being at the level we are, things wont always be "peaches and cream", there will be aspects that wont please all the people, that is just the way it is. As Ron Tyler put it, a thick skin is a good thing for all HybridZ members. Also, keep in mind that this site is maintained on many levels behind the scenes so that it can run 24-7 for all of us to enjoy and the admins are NOT getting paid to clean house and play babysitter.

…Still haven’t found those darn shed keys… Must of left them over at “trysearchingfirst.com”… (BTW Jeff, good one... lol)

Who wants to field this one while go find my Tool Shed keys?.. I’ll cuff and stuff this one when I get back.. “I could’ve swore I left those darn shed keys on the counter next to my flashlight… “

EEWWW… That pic gave me the eeby jeebies.. Yes sir the rats are WAY more fun. At night, button activated tactical lights on our rifles, literally thousands of rats in the multiple barns on this dairy farm, (over a 1000 head of cattle). We just listen for the squeaking.. pull the rifle up to your shoulder, position your head for a good site picture, (its almost pitch black), squeeze the tactical light button.. you now have approx 1-3 seconds to get your shot off before they run startled from the light. We use RED lights to preserve our night vision and the red makes it easy as you just have to put the cross hairs directly between the red dots, (the rats eyes glowing red from the light), and squeeze off your shot. YEE HAAA!!! … Before we take ANY shot, we make absolutely sure of our back drop as we are shooting amongst the cattle in the barns, i.e. don’t shoot the friendlies.. Typical range is between 2 feet and 15 yards to target, sometimes as much as 20 yards to target. We usually come out with between 40-60 rats on a hunt between the two of us. Every once in while we’ll get a mouse as well. Mice are VERY hard targets to hit as they are quick and always moving. Got some GREAT stories from our rat safaris. One of which is my hunting partner, a good friend from Iceland, decided to go on one of our hunts in shorts, tennis shoes and booty socks. Normally we go wearing heavy pants/Car-harts, boots, long sleeve shirts, etc. Tennis shoes and booty socks is not a good combo, (and he proved it this night), as on a regular basis the rats will run towards us and up over our feet! A very oogy feeling when they do that as you don’t know if they are going to climb up your leg or not, thank goodness they have never done that, they just run over our boots and scurry on. Any how, this night started out as any other rat safari, RATS everywhere. My partner, Bruce, takes a shot at a rat down a narrow board walk and wounds this rat and it runs toward us. Common practice is try and stomp on it as it runs past to kill it. Well he tried to stomp on its head, missed its head and stomped on its ass. The rat not liking having its ass pinned to the board walk with a Nike, reared up and bit him on the ankle!!! He let up and got another shot off killing that rat. I grabbed a quick picture of the rat and my partners bite, (as a momento/reminder of why we should wear to BOOTS!). That hunt ended quickly that night as I bagged the dead biting rat and drove my wounded partner to the ER driving at Mach speed in the Q-45. We arrive at St Vincent’s ER in Beaverton at midnight where the staff that night had a good laugh over the Icelandic Rat Dancer stepping on his dance partner. They didn’t need the rat to check for Rabies, so it was tossed in the trash, they cleaned his wound and told him that no reported cased of rabies from a rat bite have been documented in the PCNW, but infections are common, so they cleand the bite real good gave him some antibiotics. Any how, Rat Safaris are a GOOD time for sure.. “A few RATS…” “The infamous Rat bite…” “A couple of my other Adult Air guns in full Rat Tactical trim.. “

Big Game rifle hunting this afternoon (graphic) HAHA.. I bet you all opened this up truly expecting graphic pictures of BIG game hunting huh? Well, I did do a little hunting, sort of, but not big game. Just taking a break from working in the shop to enjoy one of my other hobbies, "Adult Air Rifles". Today, plinking spiders in the pasture with the .22 cal PCP, (Pre Charged Pneumatic). I know, its weird to actually take time out of the day to shoot spiders, but it is relaxing and more like casual plinking. In the past I would hunt sewer rats in one of the local dairy farms from time to time, highly entertaining. Got some great graphic pics of our take from a few of our Rat Safaris. Also have some neat "through the scope" pics of various targets. Rifle for todays plinking session; Air Arms S-200-B Pre Charged Pneumatic Target Air Rifle, .22 cal, 10 shot magazine, 40 shots per fill at a muzzle velocity of 712 FPS with JSB Exacts over my chronograph. Scope is a Bushnell Legend, 5-15x40 A/O Mil-Dot. Pellet; this particular AA S-200-B prefers JSB Exacts, though also shoots Beeman FTS, (aka Field Target Specials), accurately as well. AA S-200-B rifle Legend Scope Game; Usually starlings, sewer rats 9”-12” in length not measuring the tails, spiders, paper targets, little green army men, Barbie, stuffed BARNEY toys, other misc plinking targets! Today’s game, “spiders”! Range to targets, 12 yards. Scope is zeroed for 30 yards, cross over is at 12 yards, perfect for hunting spiders in the pasture. This particular spider was hanging off the front of my Z-31 parts car behind the barn... "Target acquired, 12 yards range..." "One shot, one kill.. Remians of target" Yee haaa...

Found some of those pics.. In watching those fly, the electric planes appear to be the most fun to fly as they are so much more graceful, smooth, less "darty" etc. The gas monsters are just that, monsters that defy the laws of physics that appear to be a handful to control, though are quite entertaining to watch. Here are few of those pics... The Biplane and olive green Piper Cub are both electric.

Ahh.. The other RC as in Rudder Control while flying? Yeah, I try to keep the plane "coordinated" during turns, takes offs and landings Does that count? No, I don’t fly RC, but a local RC club holds two events a year at the lake near our property flying RC float planes. I'll see if I can dig up some pics of those events. Looks like fun for sure.

Just realized this would be a good place to share a few of the pics I took at the Italian Gran Turismo at Portland International Raceway Monday Aug 27th. On hand were a nice showing of Ferraris, 308, a 288 GTO, a handful of F-355’s 360 Modena’s and Spiders, F430, a couple of F-40’s, and F-50, an Enzo, 575 Maranello, a lot of Maserati’s, an Aston Martin Vantage, Lamborghini Gallardo, Renault R-5, (not so Italian, but rare and quick), along with others… "ENZO on track..." "Enzo..." "F430 and F-40..." "F430..." "F50..." "Enzo..." "Lamborghini Gallardo..." "360 Modena..." "F40 on track..." "Self explanatory..."

After you get the upper intake bolts removed, you need to “loosen” (or remove), these 6 bolts under the manifold, then with some finagling and depending on how “attached/stuck” the manifold is to the gasket, it will come free. You will want to remove any heat shield that is attached to the underside of the intake manifold first. This applies to all L-6 engines and combinations whether it is a 240, 260 or 280 Z or ZX, carbureted, fuel injected, N/A or Turbo.

Well, howdy do blk-jack... What can we do for ya?

Very nice… OOoohhhh that induction….

In addition to Warren's comments, simple issues such as this can easily be found and remedied using a shop manual. The Haynes manual for the early S-30 car has decent wiring diagrams which makes tracing easy and can be purchased at many auto parts stores or on-line.

I’m Guilty of using this one here on a few occasions, DOH! I am trying not to use it anymore so if you see me using it again, call me on it. Just as MrFancypants stated, I’ve heard it thrown about SO often that it took root and even sounds normal, irregardless of my edumacational background, Here are a couple. When people talk about the “HOT water heater” in their home?!?!? Since when do we need to heat already HOT water? It’s a "water heater"… One that gets my panties all wadded up is “Freeze plug!”

Linked below is the thread referring to raising the port with a custom intake manifold, (Ron Tylers custom intake manifold which this coustom flange was derived from). Post #3 discusses this port biasing. Link to Custom Manifold..

All traditional Small block Chevy’s share the exact same external dimensions and “foot print”. What you need to be aware of is if this is the JTR set back conversion, the harmonic damper on the new engine needs to be the small one, and if which ever style rear main seal the 305 has that your donor larger displacement engine shares the same, or be sure you have the matching flex plate for whatever engine you swap in. Also, the Big Block Chevy shares the same “foot print” as the small block, i.e, the same motor mounts and bell housing bolt pattern and in the same exact location relative to each other, i.e. it drops in on the existing 305 mounts and trans, though exhaust, hood clearance, and possible damper to steering rack issues will need to be addressed. Oh, and don’t forget to visit this link. #2 will help keep other questions from getting tossed in the shed. This post is really borderline as the information you requested exists here and can be found with a simple search. Click ME for the rules and guidlines... Good luck,

Sarah, Thank you for the update. Rest assured we will take advantage of this early bird mailing opportunity. Thank you, Paul Ruschman

Hmmm.. Looks like the port centerline has been biased slightly high necessitating removal of material from the roof of the port on the head when port matching. Taking advantage of another opportunity for improved flow, I like it.
