I hope you have better luck than I. There wasn't a problem with the parts, they were all top notch. It was a problem with the machine work. Not sure if the machining was done in Mexico however the motor was assembled there. The issue that I was going to have with the dealership that I bought my motor from was that at the end of the year (2009) they were no longer going to be affiliated with GM. It was a GMC, Pontiac dealership that was being dumped by GM. I only had till the end of the year to fix the problem. I was lucky, it wotked out for me. One added note, I have a friend of mine who had bought a ZZ502 that he put in his 70 Nova. He had to take it out and have it re-honed and re-ringed as it was using oil big time. It seems that the honing wasn't done properly and was too coarse for the rings. Another problem with machining.

Good luck

cheers
Bill
