I'm happy with what I got out of it. I'm sure a bigger cam and a better PnP job would make a diff but cam,springs and retainers are about 500$ right? and i'll gain maybe 5-10hp(i dunno just a guess. for that much I could spray 55-75 wet shot right? I haven't really looked into the hp/tq gains but I can't justify doing a cam when I can spray for about the same price with more of a gain but thats just me and agian I haven't looked upgradeing the cam so please don't jump all over me on this
