http://i45.photobucket.com/albums/f61/redvetteharley/69%20Camaro/007.jpgI have a Biggs/Holley carb on a 383 Stroker. It has begun to leak on the intake and the engine has a small hesitation from take off. The only numbers I can find on the Carb are.3878261-FH List 3310 953. Can anyone tell me how many cfm it is or any other information about it? I am enclosing some pictures. thankshttp://i45.photobucket.com/albums/f61/redvetteharley/69%20Camaro/002.jpghttp://i45.photobucket.com/albums/f61/redvetteharley/69%20Camaro/003.jpghttp://i45.photobucket.com/albums/f61/redvetteharley/69%20Camaro/011.jpghttp://i45.photobucket.com/albums/f61/redvetteharley/69%20Camaro/009.jpg

Well Is was suppose to say Carburetor. The message is in the middle of the pictures. Does anybody know anything about the Bigs Carbs and if so are the rebuild kits the same as the regular Holleys or do you have to get them from Bigs? thanks

3310 is a 750 vacuum secondary carb-should be able to use a regular rebuild kit. Even when somebody modifies a carb the majority of the time regular rebuild parts still work.

Thanks very much for that information. I didn't have a clue what the numbers meant.
