340 parts interchange & performance Q

I have no idea what this engine will end up in ( more than likely an A body), what ever ends up happening it'll have a 4spd behind it... I wish my '68 was a 4spd. Being how I already have the cam & intake i'll use them, that wont be a problem to upgrade as that project moves along. I'm more than likely just going to pick up a Dart or something, drop the engine in to enjoy for a little while and use the whole thing to help finance another long term project.
