Grigg, great ideas.
I'm sure the trans is fine,Standard flex plate connection only modification was to machine the pilot bearing space out to the later large diameter to clear the nub on the converter.
I have been thinking the same thing about the cam timing. I was trying to remember how many teeth were on the cam gear. I think 1 jumped tooth would be enough to show. I've never seen a twisted cam, is it possible?
And thank you for the crankshaft idea, that will produce nightmares until I can eliminate it.
