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.

Well I have a few days and Bob @ RM says the cams will be done! I am excited this is a run down of what we have done.
one standard and one reverse rotation
2-MK IV blocks stroked and bored to--- 496's Machined by Fowler's
All forged internals Ohio Cranks I beam rods and 4.25 stroke crank
Diamond pistons 2618 forging ,compression around 9.75 Bore 4.310
Akerley and Childs Extreme bearings mains and rods
Cam from Bob @ marine Kinetics Hyd.Roller
Morel roller lifters Scorpion stainless Roller Rockers
AFR 264 Heads opted for the CNC job
Melling oil pump 10778 series
Going with a Air Gap Manifold
DUI Ignition
Revolution Marine Aluminum"wet" Exhaust Manifolds and rissers
????? Carb ??????? I Need Some Help not a race application but needs to work without any hickups
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)
