I just swapped out my Quick Fuel HR 735 VS for a Street Avenger 570 VS today as a matter of fact. I always felt that he 735 was just a bit too big and I should’ve gone with my gut feeling and went smaller to begin with.
The 570 seems great so far. I went from 11 in of vac to 16. Idles much better and overall seems happier. I need to adjust the pump shot some but it’s almost dialed in an evening.
Shameless plug, I’ll have a relatively brand new quick fuel for sale soon......

The QF, Demon, and Avenger series carbs are flowed wet. So the cfm rating includes fuel.
The older carbs: Edelbrocks(all), Carters(all), and Holley 4150/4160 are all dry flow rated. So the ratings for them do not include fuel.
What that means is a 750cfm 3310, when wet flowed will be around 675cfm depending on the jetting. So a 770CFM wet flowed carb is equal to an 850cfm 4150, or 850cfm Thermoquad without the smaller primaries and secondary air door.
A 670 is a good choice, the 570 is closer to the cfm of a factory carter AFB...

I went for 670 cfm Holley Street Avenger. I’ll report later, how it feels in the car.
