ok this is my problem im having with my truck it has a rebuilt engine not stock it been board 3.740 with Ross racing pistons head has been match ported headers and the cam was reground
here are the cam spec. master intake 689f exhaust 689f cam lift 260 lob separation 108 . So the problem im having is getting in proper time i have Alldata and i am doing everything to set the timing it runs with out a problem but it has no power i hold the brake and it just pops and misfires so i think the factory timing wont work for the cam in it i put a vac gauge on it and it is reading late timing i lost
