any 5.3 making 400+rwhp N/A with an automatic transmission. it seems like 380-390 seems to be the limit without going crazy on the truck side.

What's the rest of your set-up going to look like Blue? How big of a converter? What gear/size tire are you going to run? What's your weight. If you've covered it all before it won't hurt to repeat it, as this will make a great thread for you to update as you go along.

Well the cars an 81 malibu that weights 3500lbs with me at the reigns.
Th400, 3500 stall, 3.55 gears, and 275/60's in the rear. Last years motor was a 5.3 stock w/cam swap (lgmotorsports g5x1) same intake and a badly tuned carb. (According to a guy we will call pickle (holley genius)).
It has shitty 2-1/4 inch dual exhaust attached to stock manifolds.

Hopefully i can pull a 10.xx out of it on the spray. Last year i had a 11.7 on a 100 shot.

If I can find a set on the cheap. I almost bought a set of slp mid length ones (full exhaust) but everything ive read said the squeeze aint worth tge juice. Ive got to see if a pair of long tubes off a camaro will fit but ive been unable to find a used set cheap locally

Damn, sorry I cannot remember the exact maker but the Malibu forums should help, I think we used some old SLP 4th gen headers ok the Malibu I helped a friend build with a 6 liter.
