I am wondering if I can get an answer on the location of the counter weights on the LB7 and LLY crankshaft. I have an 04' lb7 crank shaft that has the counter weights on the ends and another new crank that I was told was an LLY with middle counter weights.
I was wondering if the counter weight location is a way to tell the difference in the two cranks?

Thanks,
Jon

GM shows the same part number for both cranks. What you have is an early crank (without center counter weights) and a late crank (with counter weights).

Hope this helps.
