Holley Carb questions
« on: June 23, 2002 - 07:55:59 AM »
I have two different Holley Carb's and am not sure which I should use. One is a 4165 and the other is a dual feed 4011. The 4165 appears to be bigger w/metereing plates between both bowls but both carbs are rated at 650 CFM. Can someone explain the differences between the two designs? I know very little about Carb's.
Thanks,
Johnny-D

 The 4165 is a spread bore design with smaller primaries to give better throttle response & gas milage they work well & are more adjustable with the rear metering block than the other carb
