Holley 2300 / weber bolt pattern?

Does anyone happen to know what the bolt pattern for the holley 2300 vs the weber 32 is?

I have a different style holley A 2280 and idk if the bolt pattern is the same if it is id like to get an adapter to put i on my comet.

Any information would be helpful

Thanks,

Vintage Inlines is your best source for info....





Since I've done Holley to Webers since I was a schoolboy,


Actual Weber adaptors are used on everything from Toyotas, to Nissan/Datsuns Slant Six Mopars, Chevy L6's etc



There is another which is handed
(Holley Weber 5200 is a handed version with the 32 mm primary and 36 mm secondary swapped around)

Each has bolt spacings 47 mm by 93 mm, but its easy to miss-read, and get them mixed up



Only warning is not to use the 50.8 by 95.25 (2 by 3-3/4") Rochester 2CG spacings, out a few mm
Nor the unsafe T-jet 50 by 90 Aisan/Nikki




Actual Holley "2300" series carburetor Bolt Spacing is 3 1/2" by 5 1/8" (Autolite 2100/Motorcraft 2150 /Holley "2300 series" 2V)

Used the trans adapt 1BBL to 2BBL adapter which is setup for a Rochester 2BBL if I REMEMBER WHICh WILL FIT A 5200 WEBBER then an adapter on top of it that converts from the Rochester to a 2300 series Holley. When doing either of these set ups I do a bit of blending to improve air flow.
