Upgrading 73 Challenger with 318.

[Fordication]

So, need some advice. My car presently has a 318 in it. I know the 360 is the more powerful engine with greater ability to increase HP. So I may have to replace my timing chain shortly. I was thinking since I am about to remove a ton of equipment I may go ahead and get a new cam, install a pair of ported and polished 360 heads. I know without new pistons I am not going to get a giant increase in power. What intake and size carb should I go with. What would be a good cam for this upgrade? What is the main differences between a 318 and a 360? Thanks

How deep do your pockets go? I have this bridge, for sale, in New York...
I think going with the 340 has more (power) upside potential, and a greater industry of parts to choose from, compared to the 360.
