Edelbrock Performer on a 318?

Yes the Edelbrock performer works fine for a 318.They even have a kit that is the intake,carb,Valve springs, cam with lifters and timing chain that works REAL good. Only problem with the change to a 4 bbl is the thing will run so much better that you won't be able to keep your foot out of it !! Hence,, will the MPG's improve?? well,,yes and no.
