Holley Carb Identification Help..

I have a Holley carb that a buddy gave me...sais its a 780 cfm, need to know if it is a double pumper, what CFM it is exactly and probably the part number or where it is located on the carborator. I know it is a dual feed square bore...but that's it. Any help would be appreciated, Thanks guys!!

3310-1 is a 780 cfm. I may not be correct, but I believe the 0884 indicated that it was built in August of 1984. The Holley site is back up now.

Your 3310-1 is a 4150(has a rear metering block). as posted, it is a 780 cfm,& has vacumn secondairies. 72 primary jets, & 76 secondairy jets(factory). Renew kit # from my Holley book is 37-332......the trick kit is #37-915. It should be a good all around carb to run on 350- 455 ci engines,with a little tuning for the application. good luck.......crazy Al
