TBI since it can constantly adjust the AF ratio

Carb since it can constantly adjust the A/F ratio.

If it is a CCC carb.

Hmm, eyeing Howell Engine's TBI kit...sounds pretty straight forward...I'm in S. FLA, so coldstarts aren't an issue...more precise fuel management/better throttle response is what I'm after.

I'm in Central Fl, happy to help if you're headed in the direction of EFI.

Default Re: Carb or TBI -- Which is Better?

I have both and they both are OK. The 94 is supposed to be the best factory TBI computer, still running the sbc 350 chip. Easy starts, bumped timing from 0 to 20 base and the Olds 350 ran much, much better. Back fired and ran ****ty below 10 base.Gas mileage is so so at 13-18 mpg approximately. Might be closer to 10 in town. My Cutlass gets better mileage even with the 403 but is lighter and not 4wd. The full throttle with the Qjet just blows the TBI out of the water, 800 cfm vs 500 cfm is tough to compare. Maybe one of the high flow TBI will compare power wise to a good 4 barrel. I did the ultimate TBI mods to the the 4x4. Both my vehicles had OD at the time and similar gearing.
