Now, not to hijack my own thread (more of a detour, really), but I have another question. Did the Ram Air carbs (the 67 numbers) have one, two or three vacuum outlets on the front of the carb? I'm referring to manual tranny units.
The carb now on my 1970 Judge convertible has the correct identification number (7040273) for a Federal, Ram Air, 4-speed, but methinks it be a forgery. It's a RA IV, 4-speed car with all other numbers matching. Also, where do all the vacuum ports go? The rear port goes to the brake booster, the right front port goes to the choke vacuum. Where does the vacuum for the ram air flappers, the distributor vacuum advance and the TCS unit come from? Also should there be another vacuum port coming off the choke vacuum canister?
The following photos show the carb stamping (What is WC?) and the front of the carb with 3 vacuum ports. Was this originally an automatic carb?
Inquiring minds want to know...

A 7040273 do not have a port for A/T or a timed port for distributor advance.
And the choke pull-off is for a 1970 non-RamAir carb. Yours sits 180° wrong.
Also the throttle plate has a plugged PCV port.
Sincs your carb is composed with parts from at least 3 different units it qualifies as a "Frankencarb".
Need pictures from all sides to see were the parts came from.
