Cam and carb selections

so working with a totally stock 1975 2
318.

There's two options for the carb.

2 bbl. Which consists of a 360 cast iron 2bbl manifold and a 2 barrel carb from a 68 383, so considerably bigger than a regular 318 2 barrel.

OR

carb and manifold from a 75 360 which is a 4 barrel thermoquad with the matched cast iron manifold.

Cam.: I don't even know where to start.

What's a good cam for a stock 75 318 that is intended to be used on the street. Should get decent fuel economy and will be used for long distance road trips.

I'm thinking stock 318/360 exhaust manifolds, dual exhaust and a 904 automatic. A Ford 8.8 will make its way in eventually because i despise the lack of rebuild parts and gear selections for a 7.25. The 8.8 will have 3.08 or possibly higher gear as this car is intended to see a lot of America's interstate highways and mountain passes of the Rocky mountains.

What's the fabo recipe?

Can always use the Mr Gasket adapter on a stock 318 2 bbl intake. Then you can put on your favorite Edelbrock 1406 electric choke carb. They run and start real nice on the 318s, with stock cams too.Then the 318 intake runners will match the ports on the 318 heads . . smooth port flow.

360 intake manilfolds on 318 heads leaves a big step there for the airflow trying to get into the 318 heads.

Was able to run 20 miles per gallon, with the 2.94 gears with this setup on a stock 318.
