This may sound like a dumb question to some but I'm going to ask it anyway.
I already bought my pistons/rods before I knew about the GT stroker kit, my questions is will that crank work with the rods/pistons that I have, are the rods in the stroker kit are a custom length?? Or would standard length rods worK with that crank??

sorry if this question is stupid to some

 

you need new everything unless you want to skip out on the .3 liter bore making it a 3.96 liter stroke only by keeping your pistons
