If the engine is a gasser, then someone swapped in an Olds gasoline engine to replace it

Exactly. There WERE a lot of bad 5.7s. Once they switched to the DX block in '81, things got better. For the most part, they were ok. I would say there's a 99% chance the original engine in that '78 has been replaced with a DX block (goodwrech engine).
I sold my '81 C1500 with a 5.7 because I never had the money for a new injection pump. I wish I woulda kept it.
As long as you don't tow much or beat the s*** out of it, a 5.7 will be just fine.
I want a diesel car, Found an '81 Lesabre with a 5.7L diesel, I can buy it this spring when the ground dries up. I can already see dual exhaust with glasspacks in it's future
