You can get a "seasoned " 4.8 out in a yard for next to no money. With lowish miles too. They just are not the ls motor everyone wants
Yup. Picked up an iron block 5.3l the other day, complete with harness, pcm, tac module everything for $350. They're dirt cheap. They're still an LS, same architecture, same cranks, different heads/intake/cam, and still make nearly 300 hp.
Yup this. FIL has 230k on the 6.0 in his one-ton van and it's going to outlive the chassis it's in. Sure it'll be heavier than an aluminum one, but it makes ~315 hp just the same. GM is also pretty good about having the PCM on a short harness that can stay attached to the powertrain when it's yanked for a second life. They even sell manifolds if you want to put a carb on, in case your junkyard LS project was too cheap.
