I plan on having a 600rwhp turbo or supercharged engine with 150-200shot of nitrous on top of that. So hopefully 750-800rwhp total. I'm still debating on a 383 or 355 if that even matters for ring selection. Do I have to have hellfire rings for this amount of power? It seems that I have heard of 600-800rwhp daily drivers, but do these same engines really have hellfire rings?

 

What's the problem with Hellfire rings??? If you're thinking that they are hard on a street motor, I really wouldn't be concerned...additionally, if you have an 800rwhp street car, you're not going to put many miles on it. Build the motor to support the H.P.
