360 crank knurling?

When the crate Hemi's came out in 2000, I believe it was Arrow putting them together. But the parts were so bad they could only assemble one a week. Chrysler got pissed and sent everything up to Cummins to put them together. My 472 was a nightmare with the problems I had, so Mopar took it back and sent me a new one. So here they are trying to save money on bad parts, with the assembly of the bad parts, and it bit them anyway. I never hear anybody else talk about this and I know I wasn't the only one to have trouble with those motors. I was fortunate to buy it from a Dealer that was very good in helping me getting the problems I had rectified.
