Barry, Blair, or I can get you some forged pistons for way under $720. 

Cast isn't bad, would be a cheap route if you're just wanting something to play with and sell down the road.  However, most compression heights of out-of-the-box cast pistons really don't lend themselves to good quench numbers.

Cast is fine in a daily driver type cruiser.
Considering every production 390 came with a cast piston.
When to step up to forged. Always a good question.
I think it is a cost vs reward thing.

Wouldn't these work for a 40-over 410?

Looks like the compression height is a good fit.

Looks good to me, I'd run them.  However, if you aren't going to keep the motor, maybe build it as a 390 and keep or sell the crank?
