Those look great! Can you do a crank like the magnum XL, but with the center coutnerweight's and a BBC snout, so it will be stronger and take the abuse of a gear driven supercharger better?

Callies Performance

Yes we can do some of that We do not do the 'XL'Profile to the billets, they have their own counterweight profiles, we can do the BBC snout.

Good to know. I like the fact that there's now a solid and attainable (without the huge wait or cost) of a center counterweighted crankshaft... the available BBC snout is great too.

When I'm ready... you'll get a PM

Sounds good!
