And less MPG. Some people do care about that, especially when they drive from Indiana to Columbus OH (that's a pre-emptive rebuttal for Swingin's 'who cares about MPG?' response, which is always right around the corner ).
FWIW, I got just as good mpg in my 340 swinger w/ the 750DP as the 625 carter. any 4bbl carb is going to use gas if your foot is on the floor. I'd guess 90% of our members have other cars they drive for "gas milage" if you want gas milage go buy a honda.
