A833 OD 340 4x4?

Hi all,

So, recently I had such a blast camping with my dogs (im on that age), that Im planning on changing my plans of a 340 street strip car to a street-very streetable-maybe off road-sometimes at a stop light go 400meters as fast as possible-kind of car.

I will be swapping the 360 i have for a 340 (I have a tired overbored low compression 360 van block that Im not in l0ve with and I have found myself a 340), and a833 OD.

So, my question is: is it just stupid? Or not so much but a little?
If a good idea: what would I need appart from high gears for power and the front Dana conversion? What Transfer case? divorced, not divorced, AWD or 4x4 etc

This car was driven in my dad's garage the same day I was born, so HELL of emotional attachment, in case someone will say "just get a 4x4".

Thanks!
