Cast Crank Strength

I'd like to know the same thing. Anyone have luck running more than 100 shot on the hyper pistons? The 4" crank, balancing, and special pistons would make it more expensive than getting a 360 short block, and getting forged pistons. I'd think the extra 50 cubes isn't worth the extra $. Maybe go 360, and then spend the extra on the upgraded axles?
I've got a stock 318 ('86) in my street duster, and I used a few bottles full and the only thing I could hurt was the 999 tranny. I'm seriously considering swapping my trucks 360 in, and it was built with hypereutectic pistons. Or maybe leaving it alone, and building a 408 out of my spare 360 block. How much cheaper are the hypers in comparison to the $500+ forged stroker pistons?
