    I owned a '68 427 Tri Power Vette. Had 9 carbs of which 3 sorta worked OK. What they did best though was wash down the cylinders.

    Never again for me. Went to a 4 barrel and engine ran MUCH better.

    More carbs the better it looks to me!
    I have run 3x2's on many motors for years and never had problems with them! You just need the right carb's and tuned right, just like any other carb setup.

    If you do a search on here you'll find lot's of good info on repairing them and tuning them.

    Really comes down to do you want to go fast or look good??? Tri-powers really do look nice, but with the extra expense and time of building and maintaining multiple carbs I'll go with a single four barrell everytime!!!!--and still love to build engines with dual fours and tri-powers cuz they are just sooooooooo kewl!!!!!

    That's the bottom line........in most cases a single four barrel is a very close match to what an engine needs and they run much smoother and troublefree than any multiple carb setup. But to me they just look lost on a hot rod, especially a hoodless one.

    So, do you want smooth or cool?

    Give me three for looks, but just one four for no problems.

    Nothing cooler or MORE Hot Rod than multi carb set-ups. I have been running them for a lot of years, not sure how much or better they are supposed to be but they are cool.

    Today there is really no reason for a multi carb set-up not to be just as reliable as a single four barrel, or just as trouble free. Barry Grant makes new 2 Brl carbs for a tri power and the Demon carbs are much, much better than anything that was available "Back In The Day". It may not be as cheap as running a single 4 brl but cool does come at a cost sometimes.
