I'm starting on my 383 now, and want to get a pretty good estimate of what my combo will run. It's a 383, with AFR 190's, miniram, 58mm tb, 24lb injectors, comp cams 240/246 507/510 lift, 1.6 roller rockers, accel spark/fuel management system with calmap software in the car. I'm also running slp 1 3/4 headers, no cat, and Hooker cat-back. 700R4 with 3000 stall, and lower control arms, and Mickey Thompson E/t streets with 3.73 with a true locker. I'm also going to put my 150 hp nos shot on it. Can this combo get me in the 11's? If not, I'm going to scrap it and buy me a new LS1 Trans AM, and just juice it and I know i'm in the 11's.
