340 or stroker?

Thanks for the input guys. I will check into the stroker kits that you all recommended. What would be a good cam for one? Right now I am running an old style Isky 310 hydralic cam. The old cam that wiped was a 310 Isky that my father-in-law (the original owner) put in, in the 70's and I called Isky up for another one. They still had the specs so they ground it. I guess this wouldn't be good for a stroker, or would it?
