I agree! It would be a wicked Z car powerplant... You meant a complete R07 engine, not just the block right? The bore centerline spacing of the R07 is 4.5” vs the 4.4” bore centerline spacing of all other Small Block Chevy’s which should directly carry over to the rod journal spacing as well, unless offset rods/pistons are used for the inner/outer cylinders. My guess is the rods and pistons do not have staggered offsets to accommodate a crank designed for a narrower bore spacing, meaning cranks and cams will not interchange between the R07 and other Small Block Chevy's, let alone heads, and other valve train components. Aftermarket support now and in the near future will most likely be very specialized and limited, probably on a race team/engine builder, by race team/engine builder basis, such as RCR receiving their own specialized R07 components. I’m sure many aftermarket parts manufactures would be more than willing to manufacture the required components for a privateer R07 build up, such as cranks, rods, pistons, cams, etc, $$,$$$.$$ Something else for the rest of us to consider is, this engine was designed from the ground up for one segment and class of racing, NASCAR! Street use or other racing platforms was not part of the design criteria, though I’m sure it would assimilate to other racing and performance arenas quite well, (fingers crossed we'll see more of this powerplant outside of NASCAR...). Add to that its newness on the NASCAR scene, (only 1 year old now). If one could acquire a complete “over timed” Chevrolet NASCAR R07 engine, you can bet the price for entry will be staggering, (unless you have buddy working for a NASCAR race team ). The SB2 variant has been run for some time now, and tons of NASCAR take out/over timed SB2 goodies are available to the general public via race shops, eBay, etc, and even the replaced SB2 is a bit of a stretch to duplicate financially for Datsun enthusiasts, let alone the all new super-whiz-bang R07. (I think the SB2.2 is till being utilized in other racing arenas...) I’m not trying to burst anyones dream of owning such a power plant. I’m sure a truly dedicated individual could scrounge a complete R-07 on a budget and make it a reality, especially someone with connections to a NASACAR team, , I’m merely trying to keep perspective, the depth and breadth of the gap between us Datsun enthusiasts and recently released NASCAR powerplant technology. I am curious, if these engines are being released to the public on any level of completion, how much $$,$$$.$$?

Don’t know if this helps or not but I did test fit a bone stock SHO 3.0 V-6 into a ’76 Z car shell a little while back. These threads linked below cover a few of the obvious aspects of the SHO-Z conversion that I discovered during the mock up phase, of that now defunct project, (would make for a wonderful HybridZ car, especially boosted!!!) http://forums.hybridz.org/showthread.php?t=94815 Several more pictures of the mock up in this thread… http://forums.hybridz.org/showthread.php?t=121961 Keep us posted.

Instead of just parroting what Brian and Jeff already said, I'll just say ditto..

Just did a quick search and nothing came up here on HybridZ concerning the new ground up redesigned Chevrolet NASCAR race engine, (year old now), dubbed the R07. 4.185” bore, 9800 RPM! I’ll take two!!! Here are just a few highlights, more details can be found in the links below... Pretty cool architecture, all new ground up design, still a V-8, bore centerline is now 4.5" vs the 4.4" of all other SBC’s. Dizzy is up front now, 6 bolts per cylinder clamping the heads down. In some of the pics I've seen after the port work has been performed, the port geometry and chambers appear to be a little more aggressive/nicer flowing vs the SB 2.2 heads. Port arrangement is no longer mirror image. Lifter bores are staggered in the new block. Revised oil and cooling passages, and the redesign list goes on... One attribute that really caught my attention was the new coolant routing as it exits the engine. It appears that the coolant still enters the front of the block as before, but now exits the heads just under each of the individual intake ports, offering a more uniform flow of coolant from the block through the heads, eliminating the need for external coolant routing, as was the norm with the previous SBC NASCAR power plant. The coolant passages in the block deck also have a dedicated transfer directly under each exhaust port as well. Here are some links and pics, enjoy… (Images courtesy of Super Chevy, HotRod, and Machine Design…) Gorgeous huh? Coolant exits below the "as cast" intake ports... The Divorced intake runners and valley pan. Note the coolant plenum cast into the valley pan... COOL!!!! http://machinedesign.com/ContentItem/72056/ChevysR07RacingEngineaChipOfftheOldSmallBlock.aspx http://www.racecar-engineering.com/articles/stockcar/168821/chevrolet-r07.html http://www.circletrack.com/featuredvehicles/ctrp_0706_chevrolet_r07_cylinder_heads/index.html http://www.webwire.com/ViewPressRel.asp?aId=32561 http://www.superchevy.com/technical/engines_drivetrain/completebuilds_testing/sucp_0712_chevy_r07_nascar_engine/index.html

Whether were racing, flying, Administrating HybridZ, you name it... Always the brides-maid…

Where did that come from?... heheheheh ....

An so there you have it... RayG1988 new usertitle...

Ok fellas, I have an idea, not sure how well it will play out, but what the heck, lets give it a try, shall we? You guys get to choose RayG1988’s user-title! (His LOLcats reference is way funny...) All suggestions for his new usertitle have to be made in this thread, by Thursday 7:00 AM Pacific time. Please give your reason for your choice including any links to posts that help explain why that title fits. I will then choose one of those usernames. I know that isn’t much time, but I’m leaving town for a few days in the morning, so…

I like it….

That was my F-prepared 240-Z race car. Here is a write up with details and a few pictures, mostly focused on the MS and EDIS installation. http://www.msruns.com/viewtopic.php?f=95&t=15436 The race car was parted out, reasons explained in the link below, post # 9. I kept the front and rear suspension with rear disc conversion for project FUZZY, (shortened struts with Ground Control coilovers and Tokico illumina struts, all poly bushings, Porterfield pads, stainless lines…) http://forums.hybridz.org/showthread.php?t=115326 Lately, my lovely wife of 19 and half years would like a Ferrari GTO replica as her part time daily driver, so the ’75 shell slotted for project FUZZY may become her L-28 powered 250-GTO. The Supercharged V-8 powertrain that is sitting on my shelves may end up in a/the Z-32.. (yesssssss…) I also have my VH45DE from my ’96 Q-45 which is in excellent running condition. I really would like a mild daily driver Z-32 with a VH45DE… The there is also this nagging itch that I am seriously considering scratching in the near future involving machining my own very short stroke single plane SBF or SBC crankshaft… (Deep breath…) decisions, decisions….

Well I guess that’s as long a title as you can have about misc automotive ramblings..

Not sure how or why some P-90a’s came from NISSAN Hydraulic and others were not. Nissan released them that way, and some people have converted others. The Nissan released Mechanical P-90a heads are not a conversion. The adjuster bosses are machined just as all other mechanical heads, no oil port to the oil galley, same stock adjusters, etc. The Hydraulic P-90a heads have larger adjuster bores, and when the converted to mechanical, will have an insert installed in the larger adjuster bore so the stock mechanical adjusters can be used. 1 fast Z may know more about this. Here is a thread with pictures of a factory mechanical P-90A, (it was a surprise to me then as well)… http://forums.hybridz.org/showthread.php?t=113246

This has been covered in depth on this and other Z car forums.. Recap; '81-'83 ZX were assembled and distributed in the US with these cylinder heads; ALL N/A cars = P-79 head. ALL Turbos = P-90/P-90A heads. NOTE!!! SOME P-90A heads, not all P-90A heads, utilize hydraulic lash adjusters. SOME P-90A heads utilize the mechanical lash adjusters same as all other L-6 heads. NOTE, part duex; ALL mechanical L-6 camshafts are interchangeable, from the first 240-Z to the last 1983 280-ZX and 1984 L-6 Maxima. The hydraulic camshaft that was available in the P-90A head can NOT be used with mechanical adjusters, and vice versa. Mechanical and hydraulic cams have very different opening and closing ramps on the cam lobes, as such, you MUST keep hydraulic cams with hydraulic adjusters, and mechanical cams with mechanical adjusters, period! Regarding this MSA Turbo cam. MSA could have very easily had typo or the ad department doesn’t have a clue about Z cars. Best bet is to contact them directly and ask to speak to a tech, savvy Z car valve trains and ask him/her if this is a hydraulic or mechanical camshaft. Remember, the only criteria you need to be concerned with is, is the cam ground for Hydraulic lash adjusters or mechanical adjusters. If the cam is ground for hydraulic lash adjusters, then it will ONLY work in a P-90A head ONLY if that P-90A has the hydraulic lash adjusters. Only a visual inspection with the valve cover removed will reveal if any P-90A head is hydraulic or mechanical. Outside of that, the casting number on the head and the vehicle year means squat diddly.

I'm not too creative myself this evening... Found this one just now…

:lmao: I just spit coffee out my nose... Visons of LOLrus dancing through my mind... Hmmm... "Noooo, they be stealin mah title..."

When I was working through my MS reset issue, in my research on the subject I did find where others have found a noisy alternator will cause MS resets. Could it possibly the alternator took dump, i.e. bad diode/s, regulator, etc? Just a thought...

YESSS!!!!!! YESSS!!!!! :lmao: Totally wicked!!!! Love it!!! We are not laughing at you, but laughing at the irony of your picture! I feel terrible that a shop did this to you and hopefully they will fix THEIR mistake! Again, we are not laughing at you. The early Z car has its design nuances, one being the rear control arms as you now are very much aware of. This is one of those things the rest of us just wish we would’ve done first… :lmao: Here are a couple shots of a Die Cast model I have of a '72 240-Z. The attention to detail on this model is uncanny, evidenced by the detail of the rear control arms. Even these Chinese model makers got the rear controls right... though the diff mount on this model is the ’70-’71 diff mounting location…

John, You've got mail...

Bones, Yeeup, you’re absolutely right. “Pretty sure” is not a definite. So I was just sitting here and I started recalling the various posts in this thread, from memory mind you, and feel I have compiled a mostly thorough list of posts that do definitely address the V-8 valve train as used in a high RPM application, or at least make mention of it. My memory is not what it used to be, I may have missed a few posts. Page 6, post #118, mentioned in #119. Page 7, post #125, #128, #130, #134, #139. Page 8, post #141, #148. and just recently, Page 22, post #421.

I have “heard” that some of the faster drag V-8s as far back as the ‘70’s will hit 10,000 RPM. Current Pro stock V-8 engines are shifting between 9000-9300 and read on one site that some Pro Stock engines will spin as much as 9800 RPM. Top Fuel 8200 RPM. Of course these drag engines are only seeing these RPM’s for a very brief second or two max.
