FYI:
= Big bore XB motors chuck out 100+ hp when built badly and cheap... So it's all on what kind of money you have under the mattress.
= 1125 motor is probably worth $$1500, you can buy whole used proven motors for $800-1000 online. 1190 motors are also available now.
= that built XB9 is equally interesting to the go fast community as the XR dirt tracker.
