so let me get this right, you are using 4' pistons in your 250 and the motor is holding together? did you sleeve the heck out of it to make that happen, or did you use some form of block filler, I thought that these motors would not last long at all even on the street if you went to a 4' piston, let alone racing on the track, anyone else think this is kinda cool, and an interesting prospect?
