The odds are its the same as the 2-21/2 ton truck engines or the combine engines probably updraft carb, and up draft exhaust.and no vacume advance on the dizzy.It may have some minor differences from application to application, but not many. Im driving around a industrial 251 in my 47 club cp.with approriate intake and exhaust, and different dizzy.nice smooth torque. I have another that Im planning on useing in a51 wayfarer [hog back]I may or may not pull the head. just clean up and change intake and exhaust.might even leave the non vacume advance dizzy in it.Im driving around now with the vacume blocked off the dizzy now, on the 251,, it works alright.So anyway, from what I have seen,I think the engines[except marine] weather they are car, truck, combine ,welder, or spray rigs ,are the same cam pistons crank heads etc.I have cranks rods heads blocks oil pumps really heavey flywheels up draft stuff oil cannisters, plus four or five more engines to pull apart when I get around to it.so Yah!! get the engine and check it out may be a good one...Christopher,,,, from the high and lonesome
