Engine verification??

[markos920]

Hi guys, I'm trying to get an ls3/tr6060 setup for my Camaro. According to seller, receipt is no longer available. I just want to make sure the engine is legit before purchasing it. I need help trying to figure out if there are ways to find out if ls engine is stolen.. My understanding, ls engines don't have the the vin number in it? Just the casting number and part of the vin#? (On the driver side) I heard the only way to get the vin is through the computer? So if the computer is missing, there is no way to track a stolen engine.. Any help would be greatly appreciated.. Thanks mark

LS VIN# is stamped on a pad at rear of drivers side on short block deck. Exactly "kitty corner" from where Gen1 Chevy block pad is located. Engine size is cast into block at rear of passenger side below. Cylinder head IE: 6.2 = LS3/L92 aluminum block 7.0 = LS7.
