If you want it to handle well stay with the small block. Back in the day as a young fella I punched out a 289 to over 300 cid. I forget exactly how large it was, something around 311, IDK. I bought several performance parts from JC Whitney in Chicago and built the engine up to over 350 hp. At that time there were dyno for engines, but nothing with rollers around to put your car on. I put it into my 67 Custom 500 and that thing could fly
! I suppose you could do a big block into your 65, but it's more Falcon than Fairlane. That's no disgrace, just that the front engine suspension is marginal to begin with. Same with the steering and brakes. I wouldn't be inclined to add wieght. I would be looking for ways to shave it off. Add to that the opinion of several folks that the 390 is a bit of a boat anchor. The newer 5.0 version of the 302 is far more powerful and reliable. Maybe get a Mustang 5.0 and five speed? Lower wieght, more power. Bound to be a winner.;-)
