383 motor swap

Yes, the Olds blocks were very strong and good, the heads were a disaster on the 350, they were stock gas heads not redesigned to handle a diesels compression. I also had to add a water separator, which should've been in the first place. The V6 were a better design for the diesel.

Olds didn't use the stock gasoline heads, they had specially designed diesel heads designed for indirect injection. The problem was that the cylinder head bolt design (four per chamber) wasn't upgraded to handle the 22.5:1 compression ratio. Often, the bolts broke but failing head gaskets were more common.

Yes, exactly, THAT was the problem. I know personally, lol. Which was not present in the 6 cyl engine.
