If memory serves me right the 350 olds diesel used a stock gas block with different heads. That being the reason they didn't hold up well. The auto makers were in a big hurry to get something on the market to get better mpg in the late 70's after the fuel shortage in previous years. They were installed in full size cars and 1/2 ton trucks. Class action lawsuits were filed against GM over these. It really hurt GM. Those were bad years.
That diesel was also installed in intermediate cars too as i had an 81 Cutlass broughm that had an olds gas engine replacing the blown diesel it came with. And that was the small Cutlass.
