Is this a good carb?

i had a 72 340 4speed challenger all origanal not rebuilt took it to carlsbad with the stock thermoquad ran 14.78 best took a out of the box holley spreadbore double pumper look just like that and ran 14.36 right off the bat. after a couple passes working with the extra wheel spin i ran 14.11 dont mean that the thermoquad was not as good but the tune on that holley was way better straight out of the box. every thing was better also started easyer throttle response was better and milage. i dont have that car anymore but since then i have made changes to th thermo and had the same succes but i have to tune them to get there.
