Well I should be getting a TPI for $100 this weekend and I`m going to run it on my 305.

What I want to know can I get it to work on a 383 I was going to go with a holley 4 bbl but now I`ll have the TPI setup.

I`ll be running AFR 195`s and a Comp cam XE286S

It'll run good with some custom chip-work and bigger injectors, but expect it to fall on it's face at about 4000rpm if you leave the base and runners stock.

I'd run it stock on the 305, then when you build the 383 pick up a StealthRam and a set of rails and stick some larger injectors in it. Then you can just swap the motors out, change the chip (you'll have to get one burned one way or the other,) and fire it up! No intake swapping necessary.

You are going to have to change the intakes or it will waste your AFR 195 heads. Might as well do all at the same time. Get a custom EPROM from say www.fasterproms.com for $350 USD. Next time you need more work, it costs $150. They will get your specs and give you a roughly working one. You borrow their DIACOM software and load it onto a laptop and get datalogs. Email it to them and they send you another chip. Take more readings and email them. When it is finally done, you send all the stuff back with a $350 check. Your lonely roads are your dyno. Anything other than this or a real dyno is not truely custom.

like theyre saying the tpi strangels even my 350 i would never put it on a 383 especially not with afr 195's thats a huge mis match, actually they dont even make the 195 any more do they? i heard it was discontinued because it was too excessive for most people who were buying it or something like that. Remember when choosing engine parts start with the cam, then choose heads that match the cam profile, then choose an intake that flows enough and preferrably just enough for your heads. Choosing an intake, then getting huge heads, and then slapping whatever cam is will make you run slow as **** for a ton of money your engine is only as good as the combination of all its parts

Nothing wrong with putting the stock intake back on it 'till you can come up with the cash for a better/different/modded one.

I ran the stock intake with afr's and aftermarket cam on the stock chip with the 383 and ran 13.70's. Could have gotten more out of it if I played around with it, but didn't.

Pick up some aftermarket runners and port the stock base and be done with it.

I was thinking of putting those simezed (sp?) runners on and porting the hell out of the plenum and base with a bigger t/b and bigger ingectors. I was just wondering after those modds if the TPI would flow enough air?

Or should I just go with the 4150 HP holley and the Team G intake?

If you don't have emissions testing, you can wait till you save up the money and go with HSR.

A TPI on a 383 is like you breathing through a MacDonald's straw while jogging. I'd go with a Stealth Ram or a converted LT1 intake.

Port/siamieze the base and aftermarket runners, and it will be enough.

My accel base is larger than the OEM one in the ports so porting it is good. Runners and intakes woudl be good. Don't go halfway with just the runners.
