The four barrel usually gets a little better mileage because the primaries of a Rochester Quadrajet are a lot smaller than the Rochester 2-jet that was used at the time.
Once you open the secondaries of a quadrajet however, you will use significantly more fuel than a 2-jet.
will a 4 barrel edelbrock fit both chevy or ford with 4 barrel manifolds
if you got a carb rebuild kit most of them have the tolerances in them. if not there are maunals on that motor on eBay for that year motor

The 1968 had 1 of 3 engines a 383 2 barrel carb, a 383 4 barrel carb, or a 440 4 barrel carb.
A four barrel carb usually adds about 20 hp.
Advertised horsepower is: 1970 is 215hp @ 4400 RPMs. 2-barrel Carb 4-Barrel carb is 225hp @ 4600RPMs. 1971 is 250hp @ 4600RPMs. 4- barrel carb 1972 is 175hp @ 4000rpms. 4-barrel carb. 1973 is 155hp @ 4000rpms. 4-barrel carb. 1974 is 145hp @ 3800rpms. 2-barrel carb. 4-barrel carb is 160 @ 3800RPMs 1975 is 160HP @ 3800 rpms. 4-barrel carb. 1976 is 145hp @ 3800 rpms. 2-barrel carb. 4-barrel is 165hp @ 3800 rpms. 1977 is 165hp @ 3800 rpms. 1978 is 165hp @ 3800 rpms. 1979 is 155hp @ 3600 rpms. 4- barrel Hi Altatude engine. 165 @ 3800 4-barrel carb heavy duty engine.
Probably not.
If its a 4-barrel carb, its 310hp. If it has the W-31 option it was 325hp. Both were considered "high compression" engines. There was a 2 barrel carb 350 cu in that had only 250 hp. Hope this helps.
