Started with tunnel ram dual 390s, never a single carb, ran extremely well but rich, hesitation sometimes.
A few years later 600s, different animal, able to tune it better for whatever reason, not rich anymore, less of a hesitation, although very slight.
A few years later efi, a different species. Starts on the coldest day with a flick of the key. Cold starts, I turn the key on, then off, then on. TBs shoot a little gas when the pump is primed, and 2 shots with the tr help it fire.
The tbs have gigantic bores, and the fuel swirls in, can hear it when driving.
No hesitation whatsoever.
No more dealing with gasoline on my hands, and if the key isn't on no pressure in the lines, easy to change filter.
No more tuning, it's all controlled in cabin. Ditched my tach, temp gauge, it's on the controller, as well as a dozen other things. Timing control as well.
No return springs needed, incorporated into the tbs, what's up with that carbs?
I drive it everyday, always have, the efi is next level. I've never bothered with the mileage I'm getting, if you have a tr and are worried about mileage, sell it.
It will cost north of the initial 2k if you do it right. Tank, in-tank pump, ptfe lines, filter, regulator if it's not included, upgrade electrical, alternator, wiring, grounds, throttle cable, etc.
Like it says, go efi.
