Which is better? For a Big block Chevy making around 500 hp--10:1 CR
Could nitrous be safely applied in a mild dose (50-100 shot) to a motor with a cast crank?

Yep, that's all the Pontiac guys had to work with untill a couple of years ago... I made 700hp NA with a Eagle cast crank. My builder claimed it could probably take another 50-100 shot on top of that, but I was worried about the Pontiac block splitting...


BB Chevy shouldn't be a problem. But with the price of forgings, I's spend a little bit more..
