92 was the first year of the LT1. How were they for mechanical reliability that year? My dad has a 96 with 80k miles and it’s immaculate, but I know that sometimes first model year designs can have some glitches.
It's an absolutely bulletproof engine (it's a GM 350 4-bolt main)
The early LT1s only have one serious problem I’m aware of. About 80k to 100k miles the waterpump goes and it kills the opti spark distributor. They’re mounted on the same spindle.
92-96 are the same basic car as 84-91, so no big issues.
