Hi all, my question today , can anyone comment on what year Chevrolet and Gmc stopped using engine serial numbers and started to use actual v.i.n numbers for there vehicles? The reason is if I am able to locate a vehicle and it needs a different engine , I won't have an issue here in Illinois getting it titled, after talking to the DMV ,I feel this would be a better way to go , instead of renewing the older and smaller engine. We want to do highway driving occasionally and feel the need for a larger engine. Thank you in advance, Pat
