dude, that cam is tiny. you have some issues elsewhere. I am running a 383 with .510 lift in mine, well .522 with the 1.6 rockers. you need to check a few things. number one, with larger cam, more air is sucked into the cylinders by the longer valve cycle. as stated before, you need to check min idle setting, reset the IAC, be sure timing is set at 0 with timing port unplugged unless you are running advance in your timing set. these are simple starts. what intake are you running? which throttle body? have you increased the fuel pressure?
