I need to ID my holley carb so I can get the correct carb rebuild kit, get it rebuilt and on the boat so I can get on the water this weekend. Unfortunately the ID tag isn't on it. I don't trust any on the local parts stores to properly ID it. Can anyone tell me how to ID this carb so I can get on the water. I believe it a 650 4 barrel. Unfortunately that all I know. I don't even know if it an automotive or marine carb. It's on a '81 260hp/350. I may be the original carb but I doubt it. I've looked it over well and there are allot of numbers cast or stamped on just about every piece of the carb. Is there any way to ID this so I can get the right kit. Any help would be great, thanks.

You can then go to the Holley web site, or a holley catalog and see what you have, and also find out which rebuild kit you need.
Thanks.

Well...according to the Holley site, a D-6910 (only reference I could find) is a 4165 800cfm carb using rebuild kit 37-1537. Then again, that could be some type of casting #...send an e-mail to Holley Tech Support. They'll be able to help.

Aparently someone milled off the choke shroud for more airflow. If it is a 4165 it is a spreadbore. w/ vac-secondaries. Can you get me an exact diameter of the primary and secondary throttle body holes? This will help me help you ID the carb. If it is a Holley marine carb the first indication is that it will have the "J" spill tubes. Can you send me a picture?

Sorry no pic, I don't have a digicam. The carb is at home so I can't measure it. Thanks for the help.

Just check your old gaskets against the ones in the kit, and use the correct ones. BTY, if its a square bore, Mech secondary, FWIW, its a 4150 model. (unless its one of a couple oddballs like the street avenger)

Talked to a Holley tech, what a waste. He said it the choke flange has been milled of then there is no way it can be ID'd. Come on you can't tell me the "Pros" at Holley can't even figure out what carb this is.
