Thanks for the catch, Scott. Not drive shaft, I should have stated crank shaft....I appreciate correct verbiage as well.  As they say in the birding world, you're only as good as your last mis-identified bird....

Re coolant changes and radiator, new rad 4,000 miles ago (10 months) and new coolant since May, and new "half pipes" from TK.  I can imagine that the engine may tax the cooling system a bit more (needle right over LED and steady).  I run Valvoline 20W 50 and premium gas.

Has anyone else on the list done this conversion?  I'm kind of interested in hearing any counterpoints to doing this conversion; not necessarily what would be a better motor option, but why this is not a good idea.  Total engine investment (engine parts and labor) = $2500.
