when you swap motors are you stating FI? also are you gonna keep the factory TPI or upgrade to a stealth ram?

seeing all that makes me think of how my 91 formula looked when i bought it and after i got it painted.

now i want a IROC agian. lol

When we swap the motors we are keeping the fuel injectors and the factory TPI

You should check out Super Chevy's "Stealth TPI" article - they made extremely impressive numbers (not just for TPI - but for SBCs in general) - using ported TPI plenums and runners, slightly ported stock L98 heads, a mild Comp Cam, headers, Fast XFI engine management, oh, with a stroker crank (turning it into a 383). It made 534 lb-ft of torque and 458 HP. And it made power all the way to 6000 rpm.

Something to think about.

Something like that may be in the future, but for now I think a 383 with a stock TPI( i know it's like having a governor) with proper tuning should get us in the neighborhood of 320 h.p. Which is plenty for a 17 year old kid to be driving oround with.

Hahaha - true that. I wish my IROC had that much power when I was 17 - or ever.

Here's some pictures of the 383 in its current state.

Those manifolds will be coming off, right?

[350 89 Iroc]

i'm pretty sure but i have to talk to my dad about that , it's one of the only thing i'm not sure about on the engine

def get some short headers. thoughs manifolds really choke up these motors.

Long tubes!

LT's on thirdgens suck for ground clearnace though.

i wish my firebird looked that good when i was 17. i bet everyone knows you at your school. lol

[350 89 Iroc]

well, the y pipe is pretty rusted and has some holes in it so when we do the swap we're probably going to replace it along it some headers.

My old Camaro has a set of Edelbrock TES headers and a 3" Y-pipe. One of the downpipes from the header has a giant hole in it though from the oh-so-careful forklift driver. Rest of the system is good. s.reef has the car now.

That, sir, is one damn fine IROC.

And a damn good thread...very well done.
