A lot of cranks have little lines machined in at about a 45 degree angle where the rear seal contacts the crank to help push the oil back in the motor. On reverse rotation these lines slant opposite the standard rotation. On the reverse rotation motor you may want to have the lines polished out or they will help push oil past the seal. Look at your stock cranks closely and you will see what I mean.

Thanks,already notified the machine shop...my Cranks are comming from Ohio Crank having machine shop confirm Straitness and finish of cranks. Whats one more thing.lol:drink:

The rear main seal on a reverse rotation engine is different than a normal seal. The grooves on the seal go the opposite direction.

Sparkplugs anyone using Iridium. I am N/A Cruser Boat max RPM around 5k dont want to change them out every month

also should i increase the size of the oil coolers or will factory be fine I am unsure of the size. I am a Closed cooling system

here is some Pics (if I do this right)

I think the std crusader coolers will be fine...you will not be turning a lot of RPM, should be good to go...
