Re: holley model 2160
Its been a few years since I ran Holleys, and my book is a bit dated. I don't show a listing for a 2160 model holley. I would pull the list # (or part #) from the air horn infront of the choke butterfly. This number will give you all the info you need about the carb. As memory serves, if the carb has two accellerator pumps ( 1 in the front bowl, and one in the rear) it is a "double pumper". If it is a "spread bore" design, then it is probably a "Q-Jet replacement" carb. Some of these were single feed double pumper carbs, and were of 650 and 800 CFM variety.
