you could not give me a Holley 4 bbl;
as far as MPG and the "buy a Honda" BS, myself, no; MPG is not "the" "#1" when I buy a vehicle; BUT I want the vehicle to get the best MPG it can--FOR WHAT IT IS! My brother had a 360-powered Ramcharger; had a holley 1850 on it; what a POS; it never seen more than 9MPG; I dropped a TQ on there and it ran so much better than it did with the Holley, it was unbelieveable- and MPG went up to 14; just by the carb swap; same vehicle, same powertrain, just a different carb. so (to a point) MPG does matter.
and every time I try to "experiment" wiuth a Holley my results are about similar; I always wind up going back to Carter.
