How do you tell lb7 from lly

[Dazed&Confused]

As title says. Is it the 8th vin? Is 1 LB7 and 2 LLY?

You can just look at the engine. the lb7 will have a blue silicone intercooler tube on the hot side. the lly will have a solid metal tube.

the lb7 injectors are under the valve cover, lly you can see the wiring harness

All I have is the vin to go off of right now so thats not going to help me at this point but thanks for those tips guys.

You're correct about the VIN, 8th digit is "1", it's an LB7, if it's a "2" it's an LLY.
04 was the crossover year between the two.
