Weber/Holley similarities?

Just wanted to know if anyone knew if the holley 2300 have the same bolt pattern as the weber carbs? because im in need of a adapter plate and i was jsut going to buy a weber one for my holley

not sure, if you'll measure the distance inbetween the bolt / stud holes on your holley, i'll measure the ones on my weber.....you'll need to measure length & width on either side, then across the flange to the opposite side
sorta like this diagram the periods being the bolt holes, the lines being where you need to measure, the also measure across teh flange like the x...

Yes, the weber adaptor plate will fit the holley.

alright thanks for clearing that up for me
