How can I tell if I have a LLY or LB7 motor? Truck MFG is 04/04. I can not find it anywhere.

Built after 01/04, LLY it is.
Also, you can look at your vin #
8th digit is the engine (doh!)
1 = LB7
2 = LLY

:iamwithst When reading from left to right my VIN# is 4, but reading right to left my VIN# is 2. So which one is right? Left to right I have an LLY motor but right to left I have no idea. Call me stupid but I would like to know.

:o: Snafu on my part.....8th digit is the one you're looking at, not 10
Example:
1GCJK33102F218959 <----LB7 truck
1GCJK33204F218959 <----LLY truck
