I'm resto modding a 38 1/2 ton. My thoughts so far is to go with probably a 250 from before they started with intake as part of the head deal. Just thought if there was a list of what vehicles different engines went in over the years it would make it easier when I start roaming the bone yards. I've found over the years that some yard folks are more noligable and helpful than others. Then some hardly would give you the time of day.
