Saw a 33K lb truck in in the truck trader but its gas has low miles on it and a decent price I think but want to now if any one has done a gas to diesel convertion in that size truck and is it worth it on truck that has only 50+K on it.Looks in good condition on photo.It has a 5+2 speed.

If you think back to about '78 or so (maybe a little later) GM tried to change a gas engine over for the pick up trucks. It failed miserably and GM later on had a huge deficit to overcome when they started building the 6.2litre engine. No one wanted one because they thought it would not hold up just like the changeover did not. I was working in the engine plant at the time. The problem was that the lower end of the gas engine was not designed to take the stress generated by the massive compression (22.5:1) required to fire the diesel. Maybe someone has figured out how to do this successfuly but I've not heard of it very much if at all. When we built the 6.2 it had an 85lb crankshaft and the camshaft weighed 15lbs the block was so beefy that the whole engine package weighed somwhere in the neighborhood of 730lbs. I was a jobsetter in the camshaft dept. as well as being in final dress assembly.

That was not really what I wanted to know But I know what your saying about that typ of switching .Our DPW had one and they went back to gas on a P/U.But what I really wanted to now is if you could put like a 3208,3116 cat engine or and 8.2 turbo in that same spot with out much rebuilding or redigning the space to make it fit.
