It started with a gascap - Project Arntz Restoration

[750hp]

The Arntz is running the smaller and lighter 153 tooth flywheel and bellhousing size. It's a billet alloy flywheel, which would be a laugh behind a tough big block, but the starter motor might be a bit unhappy if you tried to get the 153 tooth combo to spin a big cubes/big compression motor.
Of course, I only assume that any replacement engine will have big cubes and big compression. Oh, and about .770" lift on the camshaft should be just about right as well...
