The problem with using the same piston is that they will have the wrong pin height for a stoker combination. You use a crankshaft with a longer stroke and a longer rod so the pin height is shorter. Unless he has some of the new after market pistons the others are prone to cracking the skirts and are naormally pretty heavy. If you are going .030 over you might want to see if the block will go to 4.250 which is .017 over and if not they do some stroker piston in the more common 4.260, 4.265, 4.270 and 4.275 b3cause it is a lot easier to get rings for these bore sizes. We can help you with what ever it is that you might want. Thanks, Keith Craft
