Thanks for the offer, but I should have put in that I need a square bore. If I would put an adaptor, I will be hitting my hood.

Just in case you have to wait to find what you want at the price you want. I have a dual inlet, spread bore Holly top load, R 84014-1 --2864 I would give you at what ever it cost to mail, I've had it for a long time. Have a great one. Gene

I have two Holley carbs that have had the choke horn milled off if you do the leg work and can come up with numbers other than what came stamped into the air horn I would be happy to take a look at what I have.

Does the one you are looking or have two bigger butterfly's in the rear than the smaller ones in the front ?

Gene,

Thank for the kind offer, but a spread bore won't work for me.

Thank you
Robert

I need a square bore card, A spreadbore won't work without a adaptor, which I can't use.

Thanks

Red racer,

From what I can see a 850 cfm will have throttle blades that are 1.75"od. Jetting and PV can all be changed .

650 & 750cfm blades are 1.688"od.

Thanks
Robert
