Thumpr cam crap

My combo I run in my d150. 360 magnum, .030 forged flat tops with 2 valve reliefs. .001 in the hole. .039 headgasket. EQ heads worked by brian hafliger. Comp mutha thumper cam installed 4* retarded. Mopar m1 single plane. Holley hp series 750. 15/8 hedmans. 727 10" 3600 converter. 3.55's. I have no issues with it idling at 850rpm in gear. Power from the hit. OP has issues. Might be too much for a low compression teener. (My guess)
