.002 will be fine. That what my engine is set up with and it has 500+ passes on it shifting at 6800 RPMs. I just rolled new bearing in it this winter, but I think that I could have just kept running the old ones. I like them to have .003 on the main and .002 on the rod to keep the oil pressure up at the rods. do you have Mopar or Chevy size?
