I had a 4.3L V6 diesel in my 1983 Cutlass Supreme, it actually had a SERPENTINE belt system on it that I wish I had saved as it was a easy swap over to a SBO block and heads. It actually ran great for me the few years I had it in the early 90's, until I lent it to my cousin and she put gasoline in it and killed it. I swapped in a 307, and my sister drove it another 5+ yrs until she crashed and totaled it. ![Disappointed face :disappointed: 😞](https://cdn.jsdelivr.net/joypixels/assets/8.0/png/unicode/64/1f61e.png)
