Stock crank should be fine there. I'm going to be running the stock crank, guys have pushed them to 1300-1400hp. The problem is when you run the big blowers like I have or the big procharger and yanking on the snout. I still haven't seen a failure in person though.

I believe the ATK 408 that I just installed is great bang for the buck. Hard to beat in my opinion for a budget friendly forged shortblock. I haven't (and probably won't) been pushing it to see what it will take, so I can't comment on high boost/power reliability.

I think they would be worth taking a look at anyhow for an additional option.
