Attention: TDR Forum Junkies Im building a 4bt with an inline pump. The goal is 300+hp. My question is that this motor is using the same pistons as the 12v. Interested to hear if you all had the choice in building a motor from scratch what your piston and ring choices would be. by the way block has to be bored out fairly substatialy, probably around 1 mm acording to what is available from cummins(. 030 to . 040 over if my math is right)
