What did you do with your GMT400 today...or yesterday....

That guy makes his $$ rebuilding engines or selling new ones. When someone wants his shop to swap engines only - he gets labor but not the $$$ selling one.
Not buying a used engine is same as not buying a used vehicle: if you buy a used car you bought a used engine, used transmission, used drive axles, used steering & suspension system.
People who don’t know anything about cars often get ripped off buying used.

The thing they demonstrated that was so worn out in that used engine- truth is if a guy with an automatic transmission put that engine in- the worn thrust bearing would stop wearing out so fast and might last a while, but I doubt it because to wear the thrust bearings that bad usually takes over 250,000 miles closer to 300k is my real guess.
What else is gone by then? Equal compression. Hence the advice to do a compression test before purchasing
 
I was give a case W9 loader. Engine was seized. Pulled injectors, knocker loose into each cylinder. It tirned over a 1/4 turn after about a week.
Its a four cylinder.
Valve stems is rusted into the guides.
I got back to work and never had a chance to finish getting the hood removed(cab and fuel tank filler is holding it from sliding back far enough) so to get the rocker covers removed.
I have a few days off work now so hope I can get back out there and see if them valve stems can be gently made to move.
That was the problem @dbrannon79 s engine
