71 4dr Dart 318 w 4bbl

Link I found as well!

So swap to Carter thermoquad carb on this and run as is? no porting needed? add the comp cam?

the HotRod mag 318 small block build that netted 400+ hp started with the HP 360 with thermoquad and swapped for Eddy Air gap RPM intake with a holly 4bbl;

out back had: hooker 4-1 headers w 51/8-inch tubes

I dont need 400hp... but would i get a better running, more fuel effeciant, and more powerfull ride from:

Holly street avenger + Weiland Action plus + comp cam 260H + Rhodes lifters + headers/exhaust (tbd)
