hi, mopar recommends setting total timing at 1200 -1400 RPM. mine is there, !! with a big cam, you should conisider launching at 3000 RPM.the motor seems to pull from 3000 up?do you run open headers?? if so, how long are your collectors?? my total is at 36-38. we run shift loops, timing loops, launch loops/ this is where ,you try one thing at a time!!!!my combo?
