Better than tpi or stealthram??? Search for 5pp
I have a built 383 tpi motor..love the torque..dislike the lack of hp..dynoed at 491tq 330 hp..
Tpis bigmouth and siamesed runners 190cc heads...crower 00903 cam (about 230 lift)
In my search for higher hp without loosing to much torque would a 58mm tb bring significant gains? Loose the tpi style intake altogether?
Any options besides stealth ram? Single plan style mpfi?
Anybody have any proven sbc combos with over 400 tq and hp?..no pwer addr

You might consider FIRST FUEL INJECTION of Bristol, WI. It's a TPI system with huge runners. My 383 is very "happy" with it. I also use Dynamic EFI's P4 for engine managment.

Accel Superram is a great street intake with good torque and there is also the FIRST TPI intake mentioned in previous post...
Dyno comparison on many intakes too bad FIRST wasnt tested..

If you get a stealth ram and find yourself needing torque you can swap cam gears and stall for a proper setup (for shorter runners) and you will not be missing it anymore.
But My vote goes for the FIRST setup as well. No need to change many other parts and you can keep the torque.

I've an '87 IROC 350 5sp.
What all is involved to go to a 383 stroker? Block is cracked.
Will TPI get me 400-430hp?
Or carb instead if straightforward eg no hood mod needed?
Lastly am in Vancouver Canada & wondering if a crate engine is best & who to buy from? US or Canada idc whatever is a better deal.
Thx

Re: Better than tpi or stealthram??? Search for 5pp
The key to more HP is air flow, you need at least 330 cfm on each runner, to achieve that,
you need to do a lot of work.
A stealth ram ported will do it.
A FIRST out of the box will flow 300cfm on the base but the runners need help
(extrude hone).
