4" Crank in 318 or 360 - Stock Reconditioned Rods Okay?

The title says it all. I'm not necessarilly trying to be cheap per say, I'm just curious if it's completely necessary to get stroker rods or whatever for a mild build. If it's physically impossible to use stock rods, then so be it.

My 'HOW TO BUILD BIG INCH MOPAR SMALL BLOCKS' book isn't here yet and I'm itching to know.

If this has been beaten to death, my apologies; search function wasn't helpful.

they'll work fine.
