Looking into the IPAs new field stock class. Pretty simple rules 426 cu limit 2500RPM limit P7100 limit they supply a s362 box turbo that you are not aloud to alter must be stock block and head for make and model. Stock intake and exhaust manifolds. No intercooler allowed. And no de-cubing allowed. My question is it possible to get a 310 waukesha to compete with these rules? Can you get them bored close to 426? Can you get the head to flow ample amount of air even though it's not a cross flow head? Am I wasting time? Is there an official bulletin that states a cummins is the OEM replacement block (much rather go this route for ease of parts) any and all info is greatly appreciated
