Estimating power?
i have now. My new setup is a 228x232x591x591/112 cam, headers LT, u d pulley, ported 241 heads, 410 gears, n full exhaust.. I'm thinking of getting a ls6 intake to. THANKS
but those ported heads are gonna be choked by that ls1 intake. also did you port AND mill those 241's? or just port? what year is your car? stock injectors?
