Carb & Dizzy Help Needed
I have a 65 F100 inline 6 that was recently rebuilt.
Have been unable to obtain any information on either of the following items:
Carb is a Motorcraft tagged AITE TA AO L 12 single V
Dizzy is an Autolite tagged C6TF 1212
Having been informed the dizzy and carb as well as the coil should co-exist perfectly in order to obtain the desired performance. Calculations indicate this engine should need ~ 580 CFM for optimum performance.
Therefore I'm posing this question:
Are these two items properly matched or should one or both be replaced.
My intake manifold has 3 holes, two for the carb bolt down and the third for the supposed EGR Valve.
From a neophyte, any and all help would be appreciated.
Thanks

Calculations from where saying 580 CFM through a 1V carb on a six? The closest you will get to that is an Autolite 4V 1.12 venturi rated at 600 CFM. That was found on 390-428 engines before the Autolite 4300. The highest Autolite 1V is rated at 200 CFM called the Vaporizer. I would imagine 600 CFM would make a six cylinder act like a dog off the line with no velocity to help fill the cylinders.
There is a reason a six only had a 1V from Ford. Actually three. 1) it is a six, 2) are they really run at 6000 rpm and 3) volumetric is maybe 80% which some forget to put into their calculation.

Big concern is will the carb and dizzy, I have now listed in the earlier post, function properly with one another?
Thanks again for response.

Ok, then your main concern is the dizzy. Many Fords had the the same 1V or 2V carb yet different distributors depending on transmission, and other engine variables. Many times that revolved around the advance mechanism as to what felt damper and spacers, in the nose, were used to control vacuum advance. Have never seen any breakdown as to how Ford determined what or specs of the different variations. Number Dummy could check quicker than me if that part number matches up to a 6 cylinder engine since my Autolite book needs to be dug out. Was this distributor stock to the engine or not? Plus, if I remember correctly that part number is missing one more number and letter after the 1212_-_

Since my post I have managed to obtain the CFM of the carb. ~ 200. Not much but apparently sufficient as this carb was running when the owner had a tree fall on the cab and sold it to me.
May mean something to you or number dummy.
