I have a crank that I'm having trouble id'ing. It's a BB with the numbers: 3521 and an X on the first weight. The casting looks like forged steel.

Do these number mean anything to anyone ??

Thanks, KarlJay

I can't speak about the history of it, so you'd probably have to have it reground, I'm in Sacramento, CA. What would it be worth to you? I have some other stuff, heads, pistons... I don't think I'm gonna use them all.

I think the heads are big port with hi-perf markings and I'll have to check the pistons and cam.

let me know...
