OK bear with me...
I have a customer with a 2000 SS. He called and wanted + 0.030" pistons, I asked if he was sure he could overbore the block (verified it's an aluminum LS1), and he said that a local machine shop said they have done this "at least a dozen times".
Before I throw
, at this shop, I just wanted to triple verify with the experts.I can' t throw
at my customer because he spends lots of money at the dealership, and I think he just doesn't know any better.Thanks
