Either today or tomorrow I can check to see what the clearance looks like without the block saver.

Aluminum bells are certainly cheaper than steel, and though I've never experienced a clutch/flywheel explosion, I like the piece of mind with the steel bell. My Skylark has had one since I put the TKO-600 in back in 2008.

I will likely run a Zoom clutch, like I have in my Skylark. As for flywheel, not sure. I've been told there are ones that will bolt up correctly to the OHC, but never given part numbers or found one that does. I've been buying new internally balanced SFI rated flywheels off the Summit discount shelf, and have two Pontiac and one Oldsmobile one, and of course none of them will directly bolt up. Right now I'm looking at using the Olds one with a hub spacer and new bolt holes drilled for the OHC crank bolt spacing. I 3D printed a template and have drilled the pilot holes but not the big holes. I consider this a sub-optimal solution, so if you find a part number on a flywheel that is bolt on, or just needs a hub spacer, then let me know!! I currently have a SFI Buick 455 flex plate (that I got free) on my OHC using a centering hub spacer and new bolt holes drilled.
