You need a flat sealing face. The conicals will help as they "embed" and turn it into a gasketted joint, and not a metal seal.
On hydraulics running 6kpsi I would sometimes lap the tubing to smooth it if I could see divots or imperfections.
I did this with #600 or 400 wet-or-dry cut in an arc to fit on the face of a spare fitting, and then supergluing it in place. I would dab a little oil on the face, tighten the fitting to the tube with the flare nut lightly with my fingers to align it, then carefully "sand" my way around the face checking occasionally until I got a "clean" tubing flare face.
It worked really quickly on hardened aluminium aircraft tubing, it took longer on steel and SS line flares. Just move around evenly and you may find you don't need the seals at all. A metal-to-metal fit is preferable to a gasket being in there.

So the contention that 330hp will punch a 240Z to over 150mph without G-Nose, Undertray, aero help.
I'm not hung on the dyno numbers, I'm hung on the physics of the basic calculations based on known figures like Aero Drag, frontal area, altitude density at 4400', etc...
The calculations have been previously done for the car as configured when run at Bonneville. (Aero Forum Here)
I'm just saying that I hope to hell someone would make more than 400 with 320 per port and 400cc's more!
And I'd welcome anybody to enlighten me what Rebello's engine was actually making to punch that S30 to 173mph at Bonneville. It was more than 330 is my bet.
Wether someone's dyno is better or not is not the issue.
I want to know how Rebelli somehow bends physical laws regarding drag horsepower at speed merely by installing his engine.
As an S30 with 345hp is limited to around 160 by drag alone.
And Burtons car is not as low as ours, so he's got no cheating advantage there...
If you want to knock others work and call BS on their claims, impartial instrumented third party tests which seem to support their claims can not be so easily dismissed, sir!
How do you explain 170+mph if the engine is not making that kind of HP? It's a two way run AT ALTITUDE (usually meaning down on HP compared to sea level dynos), no tailwind or downhill advantage. As close to theoretical conditions as you can get... And which for over 50 years has proven a hard taskmaster of Physical Laws when it comes to the rigid HP requirements to reach speeds over 150mph...

When a kid selling chocolates in the Target parking lot says " uh yeah, we're selling chocolate. But I just wanted to ask you what kind of car that was..."
(Yesterday, Moreno Valley CA. about 10 miles from where the girl at the Circle K says to her boyfriend: "Just like in the G6 Video, except just not shiny!" Boyfriend says "What's a Datsun?")

You touch on it Padawan, but your training is not yet complete. You are still impulsive. Time it take tonunderstand the ways of The Force...
Especially if you wish to avoid any imperial entanglements...

Wow, that looks incredibly complex for 600 HP, or is the plenum one the 600+ unit? The ITB looks N/A. That HP can be had at half that boost (15-17psig) and with a stock L28ET intake manifold that took a little trip to extrude hone!
That one used a Z32 ECU with matching Z32 trigger wheel-the Nissan optical triggers (at least the Z32 JeffP tested) were stable with no spark anomalies and reliable triggering to 12,000 Dizzy speed (that's 24K crankshaft speed!!!) Nissan made some really good optical triggers!

Well, you can make any dyno claims you want, but physical laws say the Rebello 3.0 that pushed Car#7770 to a new F/GT record at Bonneville at over 173 mph would require a smidge more than 290 at the rear wheels to punch a .465 cd, 22cf frontal area Stock Bodied Non-G-Nosed S30 to that impartially arrived at speed.
And that was on 45mm Webers turning engine speeds quite a bit lower than ours...
HP rating is HP rating when dealing with top speed at Bonneville. There is no dial to twist or smoothing algorithm to tweak to give a number good for sales.
Tell ya what: I'll accept a similarly prepped S30 running in SA at similar speed as proof that yours measures up to muster.
I would hope sure as he'll you make more than 400 HP with a claimed 312 per port! That one had stock valves and around 230 per port!

D'OH! totally forgot about soda blasting! Terrible when you consider I have the Harbor Freight Soda Blaster here at the house! I got the big one when it went on sale.
Stay away from the throttle bores, light solvent only. There is a thread on the throttle plate sealant when Derek was making his ITB setup.
It (soda) gives good results if you have a compressor.

I would bet your radius is for making you the casting cores easier. Mine all have been bored to the throat diameter of 44/45 Carbs.

90x89? Sounds familiar!
The RB head is a new twist, any reason you went with the 26 over the cheaper / plentiful RB25 instead?
Interesting. This bears watching.
An FYI, 400+ is available with 3L 2-Valve Head for around 7,500usd from Rebello.

There is.
I'm revealing as we speak.
Did you get it?
-
That should be on stancenation for sure.
There you go!

I've never bought anything from David, but I have had dealings with him in person during high stress periods, and can say he conducted himself calmly, fairly, and in the best interests of all involved. I would not hesitate for a second when dealing with him, and if he says something, I'd believe that is exactly the way it was.

One of the reasons I moved to SoCal was I'd read the published school pricing, and CA was unreal compared to the Eastern Establishment Schools. I remember students protesting in the early 90's here in CA that the price for a years tuition and fees had risen to the level of a single SEMESTER of my school back east, 10 years prior!
I've terminated interviews with prospective hires with the simple question: "What can you DO?" usually followed or precipitated by a stated salary requirement that I could pay to poach a competitor's functioning personnel rather than have an overvalued glorified trainee...
I remember a guy who worked in the Service Department at a Major Multinational Compressor Company, we were idly chatting while he rebuilt a little 5hp garage compressor. I asked what degree he held, expecting to find another BSME, but got "Masters in International Finance and Banking" More than a little shocked I said "bit out of your specialty, isn't it, overhauling compressors?" he said with a resigned serenity: "Oh yes, I have all my Theory now-but now I must obtain practical knowledge. Perhaps in 5 or so years I can work with you on XX-Line units! Or, perhaps if an opening presents itself in Finance with the company, I can apply there."
How many guys in the USA or anywhere do you know someone with a Masters Degree willing to take entry level dirty-hands work to bide their time hoping for an opening within their specialty in a large Multinational? He was likely paid in the area of 600 monthly...
I often wonder how he fared, they closed that branch soon thereafter... Like large multinationals tend to do.
Don't get hung on self value, always be ready to answer that simple question: WHAT CAN YOU DO?
Hesitation in interview puts you towards the bottom of the stack, if not to the top of the circular file.

I transferred the entire contents of food stock from the McD in Tawas to Oscoda when the freezer took a dump. Over 2000#!!! 17 miles, and then two trips to transport it back two days later including the latest truck delivery... That was about 4850# !!!

Agree with theCC route. That us hoe my son is progressing. I figure he's going to change majors at least once and that it a LOT cheaper in CC than full-inn colleges.
My sin had a lot of interaction with the UCR Engineering Student Teachers, and was always at their lab. So he's going to RCC which is a fully compatible and transferrable institution to finish his last two years at UCR.
Though several members of the local Z Car Club (as well as dad) kinda are leaving him Cal Poly Pomona Propaganda...LOL

That's a rather recent conversion for the A/C, judging by the new sticker and small compressor.
Used A/C is not usually worth much since new kits are under $600...
Same with cruise, kits at Auto Zone or Pep Boys are under $200 new.
Getting half back on either and you would be doing good IMHO...
Good Luck!

Don't you mean: "Ahhh So-ka, Desu!"

"The percentage of my former professors that I would ever consider hiring is much less than epsilon. "
BWAHAHAHAHAHAHAHAHAHAHA!
"What I took away from the experience is that if I needed to learn something, I was on my own to find the resources to learn it."
We all share your pain, and it is the root of the "SEARCH NOOB" flamepost!
"Self, why is this guy here? He's got a PhD in an 'in-demand' field -- why isn't he making wheelbarrows full of cash in industry?"
BWAHAHAHAHAHAHAHAHAHAHA! Do you recall "Ghostbusters": "Venkman, you haven't worked in the Private Sector, I have! Those people want results!!!" That kinda sums it up, but I kinda think you figured that one out on your own!

The plenum is sized down for more 'modulator ring' action when used with carbs.
Other than a brand new plenum, I don't think I have EVER seen one in that condition!
Porting to match the ITB's is what you want to do, there is nothing to be gained on an ITB with the restriction.
Then again...maybe I should trade you 'cause if I ever decided to do a carb setup again, just for retrogoodness and car shows...
What am I SAYING!?!?!?!?!
Port it!
I can send my photos of my ITB's if you send me detailed photos of yours!
(As soon as I get them back from PALLNET, who is currently making fuel rails and vacuum logs for me and 24OZ here... We have identical setups on Mikuni Manifolds.)

I got lots of parts...

Yeah, I keep forgetting and the assortment kit has two sets in it that will work.
One set is 'too long' and you sand the small ends down.
The other set is 'too short' as it won't bush the shifter all the way through, but it works for someone who comes to your place trying to sponge something off you for nothing.

Time limited. I had scanned a bunch of my 80's slides in the week I was home before Christmas, but many of those were 'bad scans'...
Doing those albums will be more involved as they are physical photographs in many cases glued to heavy paper. I may have to go to a professional print bureau with a large-format scanner (or one of those old newspaper cameras!)
I gotta go check how they lay up the litho for papers these days.

"Sand" will cut the metal.
Glass Beads will clean without displacement.
Both will leave abrasive residue, which will have to be washed/flushed away.
Walnut shells will clean off built up junk and preserve the factory die-casting character.

Knife Store, Cabelas, Bass Pro Shops, Sporting Goods Store, Industrial Supply, just about anywhere. You use them for sharpening knives...
Millwrights use them to 'stone gasket surfaces'---basic millwright practice. "Stone all gasket surfaces whilst cleaning"--use of the stone shows off high spots, knocks down nicks, and cleans the surface to a nice surface finish that will hold a gasket better than one that is highly polished.
