Wife and I just bought a long travel rail with the aluminum GM 5.3L in it. DMV is being difficult and insists there must be an engine number on the application for registration. I've looked on the engine and all I find are two numbers:
33100828 (Casting number)
P50102 (Not sure what that is)
Any tips on where to find the actual engine number?
If all else fails, I'll throw the casting number on the form and that will probably fly.
Getting down to the wire here. We need this thing registered in our name for this weekend...
