Question:part number for Edelbrock carb

It should be on the front left side of the base.

There are numbers on the left front base '1287 9637SA' but nothing that relates to a part number.

That should be a 625CFM Carter AFB for an engine with EGR. I have one on my Ranchero. This is NOT an Edelbrock. If it were an Edelbrock the first 4 numbers would be by themselves with some space between them and the rest of the numbers, and they would be the same as the model number for Edelbrock. Such as, 1406 xxxx would be the fuel economy 600cfm with elec choke, or 1405 xxxx would be the performance 600cfm with manual choke.

9627SA is the code for Carter AFB 625cfm without EGR, 9637SA is the code for Carter 625cfm WITH EGR. The EGR carb has a few extra vacuum ports on it. One directly under and part of the choke system which when not used on an EGR engine should be connected via vacuum tube with a small port on the left side and to the rear of the carb, right on top, directly next to where the air filter base rests. The other is a large port coming out the left side on top sticking up and out at about a 45 degree angle. This port should be plugged when not used on an EGR engine.

Everything from Edelbrock is interchangeable with the Carter AFB's EXCEPT for the metering rods. Edelbrock uses a two step rod while Carter used a 3 step rod. The Edelbrock rods will work, but the carb will be hard as crap to tune perfectly, and since Carter went out of business a few years back, you can't get parts for them unless you're REALLY lucky.

Hope this helped. ;)

If you rebuild this carb, I would suggest using the specs you would use for the Edelbrock 1405 model as this is the closest thing Edelbrock has to that specific Carter AFB.

My Mesteno is blue inside and out.

All the tubes and connectors are as you described, well done! Is there any way to improve on it?

I took a picture of the carb to work and a fellow employee looked at it and said it was a 625 Carter AFB and he gave the last metering rods to his brother :(

Thanks for your advice.

LMAO! If you've seen Hidalgo, you might remember the scene where the origins of the name "Mustang" is discussed. It means "untamed". Of course it could also mean "feral". I prefer the former over the latter.

Not that I know of. Tune it like you would the Edelbrock 1405. For metering rods I think you're screwed. You can use the Edelbrock rods, but they won't work as well as the "manfacturer" originally intended. I use them in mine since the originals are LONG gone and you HAVE to have something in there to make it work.

I got the car from a mechanic and he said it was tuned for economy. If I wanted to tune it for performance, I had to make a couple of changes. Back the idle mix out one full turn each and reset the distributor to "this" position. If you don't like that setting, just change everything back.

Have not got that far. The car is already fast.

No, to tune that thing for performance you're going to HAVE to change out the jets, AT LEAST. Especially if you're gonna bump the timing. The idle mix is exactly for what it sounds like. "idle". When you put your foot in it they play no part in the way that carb runs. The jets and the metering rods take over. The idle mix plays some part in cruise mode, but other than that it's a great tool to keep the engine running while it sits at a stoplight and help you pass emissions.

It may already have performance jets and rods. No way to tell. The only stock part of the car is the body. The car is too old for smog checks. Should probably have it put on a dyno and see what is up. All I know for sure is this car is really fast.

Yes there is, but you'll need a magnifying glass and you'll have to take off the top of the carb, (REALLY EASY). I'd pull the carb to do this. It CAN be done on the car, though I wouldn't suggest it. The size of the rod is stamped in the side of it in extremely tiny numbers. Same as the jets (except on top of the jet). these numbers correspond to an Edelbrock part number which will tell you EXACTLY what you have, so there is zero guessing. write down the numbers and call Edelbrock and they will tell you what you have and can suggest necessary changes if necessary, though they don't like suggesting anything for the Carter Carbs. Tell them it's a 1405.
