Holley Changeout

[all motor]

as Jim said-proper tuning makes a big difference-I changed from a dp650 after it would never run any way other that rich - to a 670 street avenger, now can start cold with no choke-faster warm up-plenty of power-mileage went from 12mpg to 18-20

I'm running a BG race demon RS sleeved for 1050cfm and other than not being able to find parts right now I have had no problems with it.

..thx. I probably should have indicated that I'm not having problems with the Holley other than a bit rich. The change out of the current carb is driven by other factors not related to trouble and poor performance.

However, before I replace the carb with another Holley, my intent in starting this thread was to get input from individuals who have the other brands installed on their cars and their experience with the brand after the installation.

X10 on the QuikFuel Carb. Love it.

I did just the opposite with a Demon 570 dp on my first FFR.

I have one of these guys reworked holley anhttp://www.performancecarburetors.com/d its great. I used them because the guy who did my conversion from efi recommended them. That being said I still agree with others who say to buy if from Brent. He helped me out a lot with some clutch issues.
