Yep, you're gonna have to start another thread for that one! 65 was the first year a 232 could be ordered, but most still had a 196.
Interesting tid-bit on the 65 American: you couldn't order the 232 with air conditioning. If the dealer tried to order both (seems like a natural!) AC won and the engine was bumped down to a 196/2V. There wasn't enough room under the hood lengthwise to fit the AC condensor and the much longer (than the 196) engine. To fit the 232 in the radiator had top be moved forward 1.5"-2.0" and a special short shaft water pump made.
If it had a 232 one of those little blowers or a turbo would be nice under the hood, but you already mentioned this one was gonna be something special, so I bet it's a V-8. But I can wait for another time and thread!
