Thanks guys,
I think I will try the crank as is, 60/40, and just watch it real close and try to see how it acts after I run it in a bit. If it doesn't behave like it ought to then I suppose I could always go back in with a crank from the Patrick's source. I don't plan on maxing out the revs on the engine, but it will more than likely see some highway speeds 30-40% of the time. Thanks for all the input.
Frank, I will consider trading out that PTO...if I can't find something cool to do with it.

Seems like a really neat feature to have. Do you think it would be possible to rig a shaft out the rear of the truck to feed PTO driven items like a log splitter? Hmm?....
