Sounds like I would have ben better off with the stock 183,000 mile chain. I bought a chain set from intense to put on my new motor but it is a JP set identical to what just failed. I guess I will return it and get one from GM. I want to run the balance shaft with the VS cam because I've heard it is smoother. The car is a daily drive and I hated the 3" exhaust, I had to put restrictors in tips to get rid of the annoying resonance at 1800rpm. I believe removing the balance shaft could be annoying also.
