318 Stroker Build
normal stroke is 3.31, your adding .69 inches so your piston is going to travel .345 inches higher in the bore. youll need pistons that are ~.345 shorter in compression height. Here are 2 pistons, one is stock, one is a stroker, see the difference? a stock piston on a stroked crank will hit the head. On a ultra low compression 318, its almost possible to run a .060 head gasket and make it work, but it would be close and of course you'd probably pop the top compression ring.
