Hi, i am thinking of changing cam in my combo is 422 4.100 bore 4 inch stroke 12.8 comp 2.1/1.65 valve 355/260 cfm @750 369/272 @900 on a 45 degree seat Minimal CCA is 2.88 made 751 hp 7700 current cam is 050 278/282 020 316/322 .200 196/199 lobe lift 444/435 109 l/c 103 c/l and with a 220 hit made at 7200 1006/800 lbs i was thinking going to 52 seat and more lift and less intake duration what extra power it would make aspro with a change.

What rocker ratio you got???
I'd leave the intake duration alone and add exhaust duration, also widen lsa and int c/l
Thank's for the reply, i have 1.8 on intake and exhaust take lash and deflection about 755 net lift.I know widening l/c will increase peak rpm but do you think decreasing cylinder pressure will hurt power
