72 Nova 350 to 72 truck swap

[stynchrr]

I recently purchased a 72 short bed 2wd that originally had a 6 cyl. The previous owner swapped a 350 from a 72 nova into the truck. My problem is the 2 barrel carb is gone and I need another. After looking at various part sites on the net i realize the carbs are different from the nova to the truck. I was wondering what other difference there are between the 350 that came in the nova and the 350 that came in the truck. Also what carbs will bolt to the stock intake if i decide to try the after market.

My intension for this truck is to keep 350 with the 2 barrel for awhile till i get everything else done on the truck (which could be a long time). So getting a cheap carb that would serve the purpose is what i am looking for.

One last thing i want to do the HEI swap on the distributer what junkyard parts are the best to ask for to get the parts?

Any thing to point me in the right direction would be appreciated.
