Heavy 68 satellite. automatic 3500 stall 3.73 gears. 470 low deck, trick flow 270 heads. 10.5 compression. Indy 400-2, tti headers. Cam is mechanical roller 264/270 at .050. .660/.630 lift 112lsa. ground straight up no advance. I know its not optimum but I have it lying around. Would you install intake cl straight up at 112 or advance or retard a few degrees and why. Also have an old isky mech roller 272/272 .050 .630 on a 108. Just want to use what I have on hand for now. Thanks, Galen

The 264/270-112 isn't ideal either IMO. If its really only 3500 flash stall, I'd expect something about 10deg smaller on a 108-110 would be quicker in the car. 68 Satellite, 383 with stock 906’s, 3550lbs, 11.18@123 Dealer for Comp Cams/Indy Heads

Only reason I am holding off on a new cam is I am hoping to go Holley HP efi. I know that will require a matching camshaft when the time comes.
