Hi guys, I been battling this for awhile now. 383, No matter what I do, It dont like more than 30 degrees, Runs decent tho, Has a retrofit cam kit in it, if that matters, crank gear installed at zero. MSD distibuter with Pertronics box, RPM heads Im running a Fitech if that matters, doubt it tho.. Actually Im running a QF right now cause the Fitech is in Cali. getting repaired, another story. No change, just dont want much timing What am I missing here ? if more info is needed , ask away. I can drive it around no problem, But I know it should be able to take more ! I should note that Im using a dialback light, I've allways used it with MSD stuff, allways worked ,I dont have tape on the balancer Thanks guys !
