i bought my brother an oldsmobile at the auction with one of those engines. i don't remember how many miles it had, but he put a ton on it after purchase. he was in florida when the intake took a dump. he changed it out in the parking lot of a building that was under construction. i remember him saying the one crew was pretty bit$hy with him asking to borrow a few tools for the fix.
anyway, after the fix, he was stationed around the country and canada, finely arriving in california. after the intake fix, and several super close oil changes, the car had over 200k on it when he sold it.
the real problems with that car started after he sold it in california, and kept getting registered letters his car had been impounded. but that's a story for anouther time .....
