Help with 451 piston choice please.

I talked with the machinist today and he told me that it would probably be cheaper in the long run to go with a full rotating assembly. Problem being that 440 Source and Muscle Motors doesn't offer their kits with the .060 overbore pistons. Does anyone know of any stroker kits in a similar price range that offer the 4.402 size pistons?

So now I am wondering 451, 470, or 512? They all seem to be about the same price. I was leaning towards the 451 but have read great things about the 470. The 512 seems to be a strict race application, correct?

Thanks
