EFI to Carb swap question

I did a quick search and did not find much. '88 formula 350 thinking of swapping to carb. This is what i can think of as far as parts:

Early f- car distributor
return style fuel pressure regulator for dialing down electric pump
intake
carb
Fuel filter
Fuel lines
Vacuum Lines

Anyone think of anything i'm missing. Thanks.

Early f-body distributor? Why do you say that? All you need is an HEI unit with vacuum/mechanical advance.

You'll need various coolant hoses, different throttle/cruise cables, gaskets, air cleaner.

Only other thing that i can think of is a throttle return spring and you'll want to run a fuel pressure gauge.

Why are you swapping to Carb? It may be a good time to change the cam also

Buy an MSD box and Pro Billet dist. Pt#8551. Plug the dist. right into the MSD and you're set.

I just swapped from a 305 tbi to a carb. It was actually easier than I thought it would be. The msd box with a msd dist made everything easier. My hardest part was to make the electric fuel pump work. It was actually very easy.
