New to V8's. 340 or 383?

I'm going to buck the trend: why not keep the 273 Commando? It was the equivalent of the 340 for 1967, it has the same kind of built-in goodies that 65cuda340 was talking about, and it's a hell of a sweet-running engine. If you're not street racing or just throwing money around for bragging rights, the driving experience is just fine. Match it with a 4 speed and enjoy the way it revs. I mean, if you don't even know enough about V8s to know if you want a SB or a BB, give it a try. You might be happy as it stands.
