Your suggestions please, I am jonesing to build.

Hey Hemied! What are the dimentions of then pistons you have? (pin size, bore size, and pin height) I have several 3.480 stroke, 340 journal cranks that I bought when IROC closed it's doors. Your set of pistons might work with those cranks. Let me know if you want to get rid of the pistons if you decide to fix the 340.
