Yeah, all the local places only stocked them for SBC cars. Even had one place say it'll fit a 400, but it was for a 400 Chevy lol

Got one online that I've bought before for another car. It's just a stock style steel flywheel. Weighs 30.5lbs. I'm running a stock style replacement clutch from Luk.

It doesn't make anywhere near enough power to warrant anything more than that, although that might change once I get the body on the rotisserie.
