some carbs requires more maintenance than others. Do you like to open the hood and fuss over of the engine ? If not, keep the Autolite carb or get the Summit Autolite look-a-like. The Autolite can go years without a bit of fussing over, maybe decades. That's if you will driving the car on a regular basis. You can't just park it for months or years either. Not going to drive the car in the winter ? Then at least adde some Stabil or even better, drain the gas.
If you're not willing to do things like that, then start modernizing the car. You WILL be diluting the classic car experience, but the pure classic car experience is like drinking Tequila straight outa' the bottle.
Exhilarating, but not for everybody.
I really like Z’s analogy as well. I get the EFI attraction. I really do. I mean, when Holley came out with that Terminator “Stealth” EFI that looks like a double pumper I had to literally slap my own hand away from the keyboard. I road tripped 2,000 miles last winter (more than halfway across the country) and constantly fiddling with the carb was a pain in the ***, as were cold starts below freezing, but I tell you what...it all made the trip more memorable.
Part of owning and driving a classic car (for some folks anyway), is having the WHOLE classic car experience. You don’t really see 911 guys modernizing their cars, and in my humble opinion, the Mustang is a fine enough beast to deserve that same level of reverence. I cherish the analog experience. I seek to increase the analog experience, in fact, with things like chassis and suspension stiffening, and my absolute favorite modification on ANY classic car, a mechanical secondary double pumper Holley; I know a lot of people HATE that carburetor, and they can be temperamental, but few things run as hard as a well-tuned mechanical secondary double pumper carb.
To the folks who say that EFI “doesn’t dilute the classic car experience”, I say, respectively, that you’ve forgotten what the classic car experience is...
I don’t advocate that everybody share in my same level of lunacy, and I suppose that there is certainly a place for “restomods” in this world...it’s just not in my own garage.
