I seen a motor for sell on ebay,its built by AZ Badboys,440stroker.Anybody know anything about these engines?(hp,reliability etc.)

 

I've heard good things about AZ Badboyz, but ive heard even better things about the HPD Exterminator Kit for the 400's. 75 horsepower.

 

I've heard good things about HPD also.I recently put on a CPI inframe,and wow this thing pulls hard from bottom up.I will get clutch kit for it next,(this pipe runs 7600-8000 rpms)some portwork is coming this winter also.I would love to see 75 hp.

 

I have the HPD race mod kit and a CPI inframe pipe and mine makes 75+HP.
