Note, if you have a C4 behind your 200 right now you do not have a flywheel hiding in there. The ring gear is welded onto the torque converter and a flex plate joins the crank and torque converter.
To do over again, I would have pushed the 200 off a cliff and gone after the 50 cubes instead. With an Al headed 250, I'd stand a chance at beating up on some Chevy guys! At least I can hold my own with some grannys in K-cars right now.
I'm sportin' a '68 Falcon with 200/C4 combo ATM.
