the thing with trying to increase compression , if the knock sensor is activated now on premium pump gas wouldn't it defeat the reason for increasing comp? what if you actually thought of increasing the cc by 1or2 in matching all the combustion chambers . you might be able to put more total in instead of what corey did with mine 24.5 total down from factory 27-28. lighter rods ok but longer means shorter skirts. which is great on women but sucks on pistons . rod stroke ratio in outr engines not the greatest stk. Cams really dont seem to mke more power unless you put a 4in piston in it to unshroud the valves. cams seem to do alot for the 402-415 and unles you just want the lope , most say cams arent worth it . pete has trid all kinds of cam in his totally ported 350 with out making any more power. thats what ive heard hope it helps. get headers and port your stuff first just might like her that way. i know i do mine
