What I have been reading tells me it is ok to use the stock cam... or to have one ground to nearly stock specs. I think it even says that in the inline power manual under the supergharging section. I am still going to replace it though.
With the 307 pistons... Would the stock cast units be more durable than the stock cast 250 pistons? I do not have $700 for a set of forged pistons, but if the cast ones simply will not do I am not going to do the build until I have the money to do everything at once!
