Order the kit from one of the Moparts sponsors - it comes with pretty much everything you'd need (make sure you have fresh gaskets, RTV etc. on hand). Getting an idle stop solenoid is not a bad idea either.

Swapping the intake on a BB Mopar is easy. Don't need to remove the distributor or drain coolant. 8 bolts and it's off.

If you're buying new carbs, they come super-lean from the factory. Invest in a few of the reusable carb bowl gaskets, bigger power valve for the centre carb and bigger jets for all. I don't remember the exact specs, but there's probably something in the tech archive section.

Again, the new carbs are set waaaaaay too lean out of the box.
