I suspect that GM's biggest mistake was to release the diesel engine in main stream cars. People weren't ready. My guess is the engines were beter than the care they were receiving. Local cab companies would change cylinder heads and intake manifolds converting the engines to gasolene when the injection system would fail, since the short blocks were still viable. I wonder how many injection pumps were ruined by pumping gasolene. _______________________________________________ Amc-list mailing list Amc-list@xxxxxxxxxxxx http://www.amc-list.com/mailman/listinfo/amc-list
