low mile 318 how to build?

And then............

Cam
Pick a cam (And spring package) with a cruise rpm range that meets your driving style/rpm @ the speed limit or what you travel at.

Carb You'll need not more than 600 cfm's to feed it. Holley or Edelbrock or OE carter(s) can do the trick well. The big secret is tune tune tune that carb.

Follow all the directions given with each package on break in and set up, clean filters etc.....and your good to go.

Have fun!
