I know on my old 77 Aspen R/T that originally had a 2 bbl, after I swapped out the intake and to a 4 bbl carb, it actually ran better AND got better mileage IF I didn't kick in the secondaries so much. Which was hard to do as a 20 something driving a muscle car in the 80s
Awesome! keeping my foot out of it may be an issue but if you’ve got it, drive it right? I just want function and any little bit that helps performance wise I won’t be mad about!
