Cast crank for Super Stock?

It's a 290 AMC, so no aftermarket parts, and pretty much nothing to directly compare. But with a light piston and fairly short stroke I've decided not to worry about it, and mag the crank after a number of passes. These are easy to internally balance.

I think the effectiveness of the damper is one of the biggest factors in crank life, but that's another thing where there is no comparable data.
