The L82 is probably a BIT more reliable than the LTI; it stands to reason that the higher the compression ratio, the more volatile an engine is (but since high compression creates more power, it's worth it). The only C3 engine I would call a piece of crap is the 1980 California-only 305. Most late 70s-early 80s 305s are both weak AND unreliable.

The general consensus here is that slick fifty is nfg, most recommend using a good quality non synthetic racing oil and or adding oil additives to improve the lubricating qualities of the oil.
