There is little difference in pass and truck 216 engines.
My 1950 parts book shows the same cam, lifters, distributor, head, and carb.
The only thing that comes up different is the pistons. Truck pistons are a little bit heavier than pass pistons.
Horse power went up in 1950 as Chev went to Rochester carbs that year, and exhaust valve and seat angle went from 30 degrees to 45 degrees for better flow.
