i was wondering if the tpi setup could supply enough air to feed a 383. i am aware of all the high-flow runners, manifold, 58mm tb, port matching, and the other tricks. would it still flow enough air for a 383 or no?

 

It will work as long as you are not trying to make a high RPM runner out of it. For low RPM street use, it is fine.

 

You will probably get better results if you changed the runners with larger ones.

 

i was figuring, bore out the plenum (there is an obstruction behind the tb), 58mm tb, slp siamesed runners and manifold, and possibly upgrading to the map system instead of the maf.

 

i was reading on another forum (www.thirdgen.org) about specs with a 383 and tpi, and showed the difference between the stock, siamesed, and other aftermarket manifolds/runners. the stock actually outperformed some of them with 410 hp, and a few of them were up to nearly 500 hp. however, when they were stock, they would complain about the lack of power past 4500 rpm. but when they were siamesed, they said power was availible all the way up to 6000 rpm. looks like ill be using the tpi setup for my 383


now, does anyone know if i can use the same sensors, computers, and wire? id prolly replace the plugs and a few sensors if i can find them, but basicly just swap out the intake and distributor
