Did all 70 model Cuda U-codes have a carburetor solenoid, even if it is a non AC car with auto transmission? I see the lead for it, but no solenoid. there is dashpot instead. The AVS is a 4617SA dated J9 which matches the build date of the car (fender tag)

The wire lead is there no matter what.

I thought the 440 four barrel did not have the solenoid but was going to double check when I got home

Yes all 1970 440 U code cars should have an idle stop solenoid (and no dashpot). That is a 69 440 4 speed carburetor you have, my gues is that it got swapped in the past.

Pretty sure a 440 auto with A/C should have a Carter AVS 4741.

His car is non-AC

Scott, since the date code on the carb base is October 1969 (J9),wouldn't that indicate that this carburetor would have been installed on a 1970 production 440 car?
Also, I have attached another picture. What do you make of the ink stamping on the backside of the body?

Pretty sure the SA at the end of the part number indicates it is a service part. Someone with more detail should chime in. By the way the 70 440-4 auto no A/C carb part numbers are 4738S and 4740S. Sorry for the misinformation on the 4741S.

As 70gtx mentioned, the SA is an indicator of a replacement (while I would not say all SA's were replacements). The date simply means that it was made as a replacement for a 69 440 after 69 model year production ended. It's not correct for your car, I'm sure on that one. Various ink stampings are commonly seen on carbs, I've seen that one on 69 AVS carbs before but I don't know the specific meaning, likey an inspectors stamp or a to quickly visually identify it (The airhorn or complete assembly) for the application at the Carter facility.

J9 is actually September 1969, the "I" is not used as it too much resembles a "1". H9 would be August 1969, K9 would be October 1969, etc.

Also, yes, what Dwight said

Were the Idle Solenoids the same basic unit that is on 6-pac cars (except for mounting bracket)?
I had heard these were made by Delco-Remy. Were they available as over the counter items as well?
Didn't Dales Cuda shop reproduce them at one point?

Cool to see a dark green '70 Cuda with the matching, extra cost bench seat.

Not all the same, the one you need is a DR1144421, they have a seperate bracket to hold them to the carb and a special lever that bolts to the throttle shaft that is required. These are not reproduced, most can be restored, cores vary in price, ebay is your friend, or try www.tonysparts.com.

that's not a solenoid. it's a dashpot that was used on smog era 4spd avs engines.

This is the correct solenoid.

Yes, Bill's example shows the one you need, here are a couple more pics, one showing the correct arm that bolts to the throttle shaft that the plunger head contacts.

Isn't this the solenoid you need?

Proper brackets and part#s yes, but being ink stamped replacements they will not have the stamped into the steel number of production line units so accordingly, are less correct/valuable. Totally usable though plus youll still need the throttle shaft lever.

What Scott said and also this,the brass cap terminal in the adjusting stud.
