How can i determine what CFM my carter AFB is buy the casting number?

and buy chance would anyone have any specs on the Carter AFB?

I have got it put back together and i was wondering if it is anything that i should know before i try to run it?

It is a spreadbore carb and i have a spacer the converts it to a square bore. Do i have to run this spacer? I am using the performer RPM intake


Thanks

Good question...I have one in the garage i would like to know aswell, im currently making assumptions based on bore sizes LOL.

 

Do you know what the carb came off of? You may wanna post the casting numbers too.

 

It came off a 1968 390 F-100. I am guessing it is a 600 cfm. I have also read somewhere an article that said they had a 670 CFM but they were very very very rare.

 

I am unaware of any AFB that was a spread bore. Rottenchesters, Thermoquads but and AFB, no.

 

I just searched for mine via google and figured it out.

 

where did you find your info ?

 

Don't recall, just some webpage that came up after I typed in the #'s
