318 2bbl manifold swap with OE cam - worth it?

I would do a small cam at the same time as the intake swap, Why pull the top of the motor apart twice ? The stock cam is aroun .410" lift so a intake/carb swap wont make a huge difference.

For a cam I would look for something like a comp cams XE262. I believe crackedback has a kit for sale right now.

Intake/carb wide, The stock iron and thermoquads work well but they arent what I would call cheap upgrades anymore. I paid around $200 for a 71 intake and 72 340 carb and the carb still needs to be rebuilt.

I think the LD4B or a Performer RPM would work well. I would run a carb around 600-650cfms.
