LS1 engine with around 130.000 miles on it ?? What do u think ?

i'd run a cranking compression test to make sure it doesn't have a busted ring land or bent valve. Remember, the car motors are much more likely to have been flogged on than the truck motors. At that many miles I'd also pop a valve cover and check for deposits. A properly maintained motor will not have sludge in the covers, just a tan tint to the aluminum.

I've also taken to running the VIN through carfax to verify miles. This only works for engines that have the PCM with them.

Personally, If it had 180 + psi in every hole and was complete with transmission, accessories, harness and PCM I'd jump on it, especially if it was the manual transmission.
