is this the bcf3 kent cam? just did a rebuild on my brothers engine with this cam, he has power output of around 150-160 but had other mods obviously been bored out to 1670 so diff pistons so not sure about your standard piston question but think it would be ok aint a mechanic but cant see there being a problem? This cam very lumpy on idle but if clearances set right there is no tappet noise if this what you mean. it is a good start for power
