No this has nothing to do with my brothers post Rolling Eyes

. Schools coming up and I see some expendable cash again soon for my engine. I was wondering what your opinions might be on twords carb or tbi set up. I found this that kinda looks interesting to me, http://www.holley.com/550-401.asp

And the cam i have says no computers would this rule something like this out ?? If need be I can re look up the specs on my cam.

Any cam that is not stock, ESPECIALLY in a MAP application will need tuning to run close to right.

Don't bother with TBI if you're building a hotrod motor. Don't even bother with TPI unless it's for torque for a truck.

Carb or aftermarket Port Injection.

Holley's stiff is sweet. But I still think it's dumb to have the injector ontop. You Can't get the proper atomization idle/cruise especially for nastier setups to make it worth my while. Sure it'll work, just not as efficient.

Cam saying no efi means no stock efi. You can tune anything. Look at Mike and I.

I've heard good things about the FAST EFI system.

And it is probably cheaper than that Holley unit. Wink

Thats what i kinda thought on the computer question thanks. So either multi port or just the carb they have this http://www.holley.com/550-811.asp , but at that price I probably just stick with a good carb

Or get the computer and look for a deal on any aftermarket port manifold. Holley uses all GM sensors. So TPI sensors will work etc.

i agree, camming a motor with map needs lots of tuning and has to be darn near perfect to run at all... my car still needs a good tune

Thats fine Aaron I want everyones two cents Razz

. Figured you guys have been at this a bit longer than me and know a crap load than me specially about the computer setups. So I like the idea of used parts mainly cause in poor Rolling Eyes

if i wanted to start tracking down parts could you give me a mini checklist of stuff i may need.

Is the 305 TPI intake and plentum much different than the 350 ? If not then I think i need to hit up doubletake.

91RSVert · Posted: Wed Aug 25, 2010 4:34 am Post subject:

TPI parts are all the same for 305/350 except the injectors.

You do have differences between the years. Also some of your vette parts wont work with camaro parts. Mainly the fuel rail.

So John, your argument is that you were not uninformed, you were just being retarded?

BTW, not only did you use the wrong runners, but you also used the wrong upper plenum. I know this because James and I where the ones who fixed it while you were off drinki...err... "playing".

Well when he only gets a 3/4 intake setup from me, sometimes things get mixed up in the parts pile. Very Happy

Bottom line, just call me and I'll let you know what store has your part. Laughing

7th injector changes in years, and the knock sensors are different 350/305

Yeah Holley wants some coin for their new stuff... but it's wicked cool and wicked easy.

Learning curve of ACCURATELY tuning the stock stuff is much much higher.

I got my old motor tuned more in one day with the abilities of the C950... than in YEARS of burning chips. Just because it was at the press of a button.

Several things change thru the years. But same year 305 vs 350. Its injectors, and also the knock sensor as someone mentioned.

Thru the years...
Fuel rail due to CSI
Runners due to CSI
Base intake due to different heads
Plenium due to map/maf (map has extra vac port)
Throttle body due to different trottle cables and tps
IAC plate (LTI plate will work on TPI body)
dual snorkle.. due to maf
boot from snorkle to TB

They still offer the C950 harness and ecu for about $800.

And those avenger setups he was looking at was with manifold. He'll need an intake with a MS system too. MS is even steeper in learning curve than burning GM chips or Branded aftermarket.

LOL yes I meant 9th cold start injector. Getting too used to dealing with 6 cylinder engines that now have a 7th injector that's plumbed into the exhaust. Heh yes it actually puts diesel into the exhaust.
