Hello Brian -

The 203 is about 50 hp., depending on which books you read. 3.6" bore, 5.0" stroke.

The 236 bore is 3.877". The stroke is probably 5" - I have no spec on it - but the math says the 236 (cu. in. displacement) is exactly proportional to the larger bore/piston area with no change in stroke, when compared with the 203 cu.in.

Hope this helps.
