1990 360 Build To Replace My Slant Six In My 72 Demon

Thanks for all the information, I really do appreciate the help. I decide to hold off on the cam until I test the engine out with the bar min changes. I got a Dual Plane intake and an 800 carb to go with it. I will probably do the cam swap a little later. My next question is would I have to change the distributor with switching to carb.
It is probably a lean burn distributor or computer operated so a new one might be a good idea.
