Help planning my mods
Fellow TPI'rs,
I hope that this string is still going. I've had an 86 IROC sitting in my driveway for years. After a few failed attemps to sell it, I've decided to restore it. It will be all original with the exception of the motor and trans. The trans is complete, I have Marsh pulleys, L 98 aluminum heads (not ported), edlebrock headers, and a few other go-fast parts from TPIS. My question is what intake should I be going with to achieve 350-375 HP while it remains street driveable. The fols at TPIS said it will never happen with a TPI because of the long tube runners. XBased on what I have read, here's what I was hoping to do:
Runners - AS&M seem to be the best compared to EDBK, SLP - including the siamese runners, (plus they make TPIS).
Throttle Body - Mixed reviews on this. Should I port out my stock 48 mm to 52 or is that at all necessary. DOn't really see why I should pay 300 bones for a new one.
Plenum - Keep stock unit just port match to large tube runners
Intake - Looks like edlebrock makes the best hi-flow out there (also make s the one for TPIS)
Please give me some feedback on what I'm trying to do, but more importantly, what you have done successfully and unsuccessfully to your cars.
