Chris; The answer is,,,, sometimes. It depends on the year of both, they must be, generally within the same decade of production. there are exceptions and lots of these kinds of pairing where done. You will have to measure the bolt mounting spread on both engines to be sure they are the same, as well as the crank shaft center line, they MUST match exactly. C model engine work every time because the CA&C share common engines. The B engine has a smaller bore and stroke, therefore less horse power than either the C or CA. If you have a later production B and an earlier CA it should work,but, do the math, the measurments will tell all. Good Luck.
