Re: 4.3L vs 5.7L ? ? ?

Don, that is correct, you can generally go to a '71-'72 (or even later) to acquire disc brakes for your project. As far as dropping in the 4.3l I don't see a problem doing so, but you can't go wrong with a 5.7l.

But then again, this is for your youngest, so I'd drop in the 4.3l and save the 5.7l for your project.
