I swapped a 216 for a 235 in my 1950 1 ton
I kept all the original accessories and even the manifolds
I swapped the harmonic balancer
Kept my old generator and water pump
Moved the distributor over
It all worked out just fine
216 block 3835327
235 block 5843350
You wouldn’t know the engine swapped
It looks like a 216 with the tiny bolts ontop of the valve cover
