QUESTION:
Im looking into getting some better flowing heads (GT40) from a cobra mustang.
these are usually used for power gains.
matched with a fuel efficient cam and roller lifters/rockers, mild injectors, could I harness the better flowing capabilities without the atrocious fuel economy usually attributed to 5.0 mustangs and the usual "racecar" mods. everyone knows an engine is essentially an air pump, and the easier it can flow the better. I already have some headers and a mandrel bent exhaust.
