I am planing of changing my 2140 carb to a newer edelbrock and thus need replacing my oil pump. Since I have a 272 i the garage with oil pump, the easiest way would be to shift it over. Without trying, is this oil pump fitting from 272 to 256..?

Thank you..//Karl-Johan
 
Are you wanting to put a 272 oil pump with a 272(+) distributor in a 256 engine block?

I've been told there are two different versions of the '54 256 engine, 'early' & 'late'. The early ones use a smaller camshaft with a different size distributor drive gear, like the 239 engines. The later version uses the; larger camshaft, distributor, oil pump parts that are compatible with the 272 thru 312 pieces. Count the teeth, 13 or 14, not interchangeable.
