Anyone have experience with RPM cranks or rods?

Just curious if anyone else here is using any of their stuff? What kind of power are you making?

Im using their 4340 crankshaft and H beam rods. I'm wanting to throw some power at my car, but honestly, I'm a little uneasy about this offshore stuff with a power adder. Id hate to get a false sense of security and it throws a rod through my Dart block at 550hp.

I had their rods in my 347, made just under 450 rwhp spinning to 7200 without any issues except a broken block...

Good to know. I'm confident in the Dart block holding up so at least that won't be an issue for me. I'm probably gonna keep the rpms to 6500 or below. Were you using a stock block? What brand of crank?
