Yea it does say that. The bolt may be good to 1500 but how about the rod. I have seen these fold over with motors making about 1000 crank hp. I would be scared with these rods. I did change the bolts from 8740 to 2000 rod bolts and I had to press in new bushings as the old ones were beat to death. I would feel better if I had some of the Scat pro I beam rods. I guess the only thing we have going for us is we are not turning the motor that hard at about 6200 rpm.
