Carter AFB and small block Chevy ID. Please help

I just received 2 AFB's in the mail for my dual quad set-up (super stoked)! Both match and are in good working order. But I need help with their numbers. I was told they were 500 cfm. So the number on the right front is 3478SA. Also I have come across a small block with numbers VO429UK on the front flat spot and 3596632 on the rear casting. All help in ID is greatly appreciated.

Thanks,
Tim

 

Any chance the casting number on the back of the block could actually be 3956632? If so, then it's a '69 307 2-bolt main.

 

I'd bet they are 600-625 CFM'S.....
most 500 cfm are Edelbrocks.......

 

I work for "CARTER" and YES, we did make 400 CFM and 500 CFM model AFB's. I have a pair of 500's on my "A" coupe.

All of our old inventory was sold to the Carb Shop several years back.
Contact them for information regarding your model.

Thanks a million for the info to everyone. The block numbers could be 3596632 if so then I can't remember if you can get a 327 out of this block. I can get a good 327 crank?
Also I will call the carb guys tomorrow for some more info. Thanks again to all.

I'm willing to bet that you have a 307 as I posted before. I couldn't find any other casting numbers close to what you posted.

307 = 3.875" Bore x 3.25" Stroke (5.7" rod)

If the block would take a .125" overbore, then you'd end up with a 327, because they share the same stroke. I doubt you can hog it out that much though.

Also keep in mind that the stock 307 uses the same stroke as a stock 283.

With say a .060 overbore, and the right cam, head, and intake combo, you'd have a pretty good all around street motor if you decided to go that way. Stock 307 SBC's***** for the most part, but they are generally dirt cheap...so you could use that in your favor and spend your money on a good matching top-end/cam combo.
