The engine and trans contain part of the VIN and I heard that it might on the rear of the frame but have never seen noticed it there.
Old school sbc did but ive been all over an LS engine and there isn't a serial that partial matches vin itd be nice if they did cause it'd make life a little easier when you go look at a row of ls engines thats been pulled out and you wanna make sure you get a 5.3 instead of 4.8 especially if your paying for a 5.3 lol and trans is a little better
