Let's go a little further, when you say "docs" are you refering to the dealership sales order form or some type of official GM form? If the selling dealer has the 4.10 listed on his sales order then it could be one of three things; Either the sales rep didn't know that the 4.10 was not available or they agreed to have it installed at the dealership. The other possibility is they ordered the car and requested the 4.10., it came in with 3.55 and they made the swap to keep the customer happy. What code is on the POP? Are you enjoying the car, hope you are. Tom
