            caterpillar:

            the AZG block is 82.5mm piston x 92.8mm stroke. we are using a forged 86.4mm crank with 83.5mm pistons and custom made 150mm rod with 21mm pins. result is ~1.9L with 9.0:1 compression.

            cams are CAT 1003756, the smaller of the solid lifter Billets from CAT.

              Any particular reason You chose to step up to bigger diameter pipe in the collector and secondary pipes?
