Fuel Help Identifying Carb...

yep, it is a 3310 which is a 750cfm carb.

by the way, it is known as a universal fit carb, meaning that it is designed to work with a large number of applications, so to get it to run right with your application you will need to spend some time tuning it.

you have a 3310 or Model 4160; a New model
the 3310 has been around a long time and has different letter suffix
The R-3310-1AAS is a model 4160 carb. The R-3310-2AAS is a model 4150 carb. In my 1976 catalog the 3310-1 and -2 are both listed at 780 cfm, while in the 1989 catalog the 3310-2 is listed at 750 cfm, as well as the 3310-3.Model 4160
the 3310 and 3310-1 are a 780 cfm carb ,these have dropleg boosters ! the others -2 and up have straight leg boosters . I PERSONALLY prefer the drop legs ,they tend to respond a bit better and are generally easier to tune . i seem to always get a lean bog out of the straight boosters. if you are good with holleys then you cantgo wrong with the 3310,or -1 . Most of the older carbs have beat up baseplates ,so be careful when buying . also the 3310 and -1 have rear metering blocks (4150) the newer -2 and up have plates (4160) . so the old carbs take the cake hands down !

This thing is way too much for this stock 302. It was on the car when I bought it.
