#1962 thunderbird code#

If by chance you have an M code engine then you have a 390 6V (six barrel) V8.

It's not over the secondary barrels because the secondary throttle plates open only at higher RPM's. The choke is over only the primary (front) barrels. If you had the Z code engine, it is the 390 4V (four barrel) V8. You just have to do it by trial and error.Ģ.

Not sure which direction to rotate distributor for advance or retard. Timing is adjusted by loosening the distributor clamp and rotating the distributor. I really appreciate it!Ĭlick to expand.I'll answer each question seperately.ġ. I need a newer carb for the added efficiency anyway.Ĥ) Carb Suggestions - I've thought about swapping for a Holley, but I'm not sure what exactly I need. Is there anything I can do to pull the idle down, but keep it going, other than doing a carb swap + vacuum system check? This'd only be an interim deal. For the engine to stay running after a fairly sudden stop (people run out into the street, have to react quickly), I have to set the idle really damn high, which causes problems when I need to cruise slowly. I think I've either got a vacuum leak, a bad carb, or both. I'm stupid, I know.ģ) High Idle - This actually involves a lot of other problems. I'm not positive on that tho, because I thought they came stock with 2 barrels, but I can see the tag on it that's the original factory tag. If so, which direction retards and which direction advances?Ģ) Carburetor type - Did these come with a 2 barrel or 4 barrel stock? How can I tell the difference? The choke sits over two, but I *think* I see two other barrels not getting covered. From what I can tell, it's done by rotating the distributor, but I'm not 100% positive. The car is in generally good condition, and runs pretty well.Īfter a spat at the mechanic (and some problems associated to that.), I've got the car back, and I've got a couple of questions.ġ) Timing - How do I adjust it. I've had it confirmed quite a few times that the Odometer reading of 89,000 is the original. I've been told compression is still good, and the engine itself isn't too badly off. I got a 1962 Ford Thunderbird last August.
