302 carburetor question

Hello,
I am putting a 302/C4 in my 1946. I have a donor motor from a 1973 maverick. The car was drivable when I purchased it. My question is, on the carburetor, should I rebuild the stock carburetor, or update the carburetor/intake. I'm not really looking for performance, just decent fuel mileage.

If you upgrade to a vaccum secondary four barrel and a true dual exhaust,you'll likely get better mileage and more power.Provided the engine is in good running cond.The upgrades will make the engine more efficient.Try to use 600cfm or a little smaller.

I'd do a cam swap to a Comp 268H, then either swap to a 4 bbl, or replace the Autolite 2 bbl with a Holley 350 cfm 2 bbl. But that's just me.
