I don't have the carb in hand but I need the find out the throttle/bore size. I've had 4 different answers from former Mopar mechanics. 2 out of 4 say the same size as the Carter BBD. Carter BBD are 1437/1063. Can anyone one help with this? Thanks

Holley list number R40276 (Chrysler number 4324647 ) is a model 6280 two barrel carburetor. The 6280 is the electronic feedback version of the Holley 2280. Both have a 1-1/4" bore diameter which is the same as the Carter BBD 1-1/4. The 6280 and 2280 share the same base mounting bolt pattern with the Carter BBD 1-1/4.
