Hi, im new to this forum and was wondering if anyone could help me identify this holley carb. the numbers on the airhorn are R84014 then under that is 3522 there is also a number on the side of the bowl and it is 12r-10658b. i was wondering how many cfms it is and if it would work with a 300-375 hp 327.this would realy help, thanks.

 

Its a 650 spreadbore.

 

ie: Standard replacement from a Q-jet with little to no modifications required.

This carb will work fine with anything that had a Q-jet on it.

 

thanks a lot, this makes the deal we got even better 38.97 w/ shipping.

 

You will want to get a fuel line from trans-dapt -TD Performance if it didn't come with one. It will be for a 4011 series Holley. The carbs have been discontinued for a few years, but holley still has kits for them. # 37-1541

 

thanks, i think a friend might have one i can have/buy
