Quick Fuel Carb
« on: August 28, 2016 - 01:08:13 AM »
is this a good deal, or is it missing too many features. Their top of the line 850 is around $850.

and both do not have secondary power valves??

The Proform carbs are a better deal, and they share the same body and bowls as the QFT.  Watch for a sale this Labor Day weekend from Mancini.

Proform also has their new street 850 with Black Diamond coating that is supposed to keep the fuel cooler.

does this "secondary idle airflow adjustment" take place of drilling holes in
throttle plates?

from what I've read annular boosters make more power
and give better throttle response.

I agree , heck of a price to pay for annular though
 you might want to look at the Holley Dominator 750 , it has changable boosters
