I have been running the scat cast crank with thier h beam rods for well over 50,000 miles and probably 700 runs at a hp level of about 400 hp at the rear wheels. Pulled it apart to change pistons. The crank was still straight and went right back in. The rods ends were round and spot on. I wouldn’t hestitate to run the scat cast crank kit with h beam rods up to about 500hp. The eagle cast crank won’t work at that level. As to the longevity of the block I was running the icon forged dished piston and changed to the flat top for compression. The bores were still round and straight when changing pistons.
