tpi for 327?

I have a 88 Trans AM with a bad 350 TPI engine. I can purchase a 327 motor. Will the TPI intake bolt right up to the motor?

Youll have to elongate the center intake bolt holes to fit,but other then that yes.And a different flywheel,unless yours still didnt change over to 1 piece rear main seal.

A 327 is a short stroke/large bore engine designed to make power in the upper rev range. A TPI setup is designed to make power in the low end. I wouldnt recommend building an engine this way, its too mismatched.

I agree with formularpm. That would be a huge mismatch.

A 327 bears little difference from a 350. They both have the same rev capabilities and will perform the exact same underneath a TPI unit. The idea that the 0.23" difference in stroke makes for a higher-revving engine is a good theory however is not necessarly true because it's more dependent on what heads, camshaft and intake the engine is using for rev capabilities.

Why can't you just find another 350 roller block? There's less hassle putting it into your car and you will make more power in the long run because of the larger displacement.

Oh, but to be able to say you have a tuned port 327.

The reason Im thinking about a 327 is because I can get it really cheap. The engine is complete with a carb intake. From just looking at the engine, it looks like somebody put in the wrench time on in with performance products. Do you guys think it would be a good adea just to go with the carb setup? Besides fuel issues, what other issues can I expect?

Carbs... besides the fuel issue.

Tuning. The carb reacts (rather doesn't react at all) poorly to changes in temperature, air density, other variables. I hate to say it, but electronic fuel injection is just far superior in terms of consistent reliable performance. I'm leaving now, cause here come the carb guys and they're mad and insulted about my cruel lies.

If you get yourself a diff intake, (HSR, LT1, Accel),or shorter runners and better flow base then you might have a great combo depending on the head/cam combo in the 327. Do you know the cam specs? If the eng has some go fast goodies I would suspect it has a long duration cam so a stock tpi manifold/ltr would be a bad combo.

as said above a holly stealth ram or an LT1 intake would be a nice intake for that motor..assuming it is set up to keep power over 4500 grand....the TPI motors peak at 4500 and fall off SHARPLY after that...but that is due to cam, heads, exhaust, and the intake design, but using TPI for the electronics and stuff would be fine, you could even throw on the stock TPI intake and then just upgrade when you have $400 or so to spare....
