3310 Holley Carbs

Also, the 3310 & 3310-1 have the replaceable secondary jet blocks and are rated at 780, the later (& cheaper versions) 3310-2,3,4 etc use the secondary metering plate and 750 rating. I believe that the later 750 versions also use the Holley manual choke setup, while the 3310 &-1`s that I have owned, always had an automatic choke. Also some of the later carbs used cheap plastic accelerator pump arms, secondary diagpram housings, and manual choke units.

And if your spec allows a 3310 then you can replace the rear boosters to the drop down for a +30 CFM gain and you can also replace the metering plate with a metering block for easier tuning.

All of my 3310-1 780s have metering plates and drop down boosters
