My motors should be back in about 3 weeks making about 600 HP a piece. So two of mine equal one of yours I do not have any personal experience with the bmax, but have heard the upper is almost bulletproof, but the lower is probably not going to enjoy that kind of torque. Wonder how a number 6 would look hanging of the back?

I thought you were building blower motors for your boat.lower gears we be ate up in about 50 hours

Yes almost put a set of 8-71 Blowers on those engines, but I new those trs drives would not last long. So I practiced some patience and decided to address the drive situation, before I supercharge.

I am sure RMBuilder minds. What not trying to email Bob and have a chat with him. You will find him nothing but professional. Next time, trust you do the same.

I have emailed Bob about my own project a year ago. Obviously the OP didnt post them, so why was it necessary for you to chime in?

I didnt realize it was unprofessional to ask for cam specs. I was just curious. Besides, it isnt like cam specs are some big secret.

that M4 is friggin HUGE !
