What would you do? Truck Needs Engine?

130K is low mileage for this motor. Known issues are always a lifter, or a gummed up valve from the DI system. So if a a valve is slightly stuck open it will have low compression. I will bet 99% the bottom end it perfectly fine. To do a lifter, heads are coming off anyway and and when you see the back side of those valves you will not believe it. Get a second opinion. An AFM delete with a new cam and lifters and walnut blast the backside of valves and it will go over 300K easily.

Incorrect cam timing will cause low compression numbers also. So if it does have a stretched timing chain and did spin a lifter, it still would all be fixed by a proper afm delete kit with cam... Assuming it didn't send a ton of metal through the system.
