Can you guys explain to me what advancing my current cam does for me. I understand raising the static CR (amount?) but will it also make it feel like a larger cam (or smaller)? If so.....what kind of numbers are we talking about? I bought this engine as "rebuilt" but did tear it down to bare block and reassemble. At that time I degreed the cam and installed straight up but I do now have a 3 position timing chain to install. I am somewhat concerned with the RPM range being 1500-4500. Not that I race it but power topping out at 4500 seems pretty low. Was told this is more of an RV (torque) cam. Thanks.
