What kind of compression are you lookin at? It should pull like a beast with just a mild cam, you dont want to go too big! Have you thought about changing the gear? If you dont want to i would say put a performer on there not the rpm, better bottom end. I have just about the same combo in my car but i have a performer intake, double humps, rv cam, 9.3 comp, 2000 stall, th350 and 2.56 gear. it spins em through first but im sideways when i hit second!
