cant believe this situation but reinstalled my TI distributor in the 427 and the tach cable (which was never removed) now comes up about 2 inches too short to connect to the tach drive. The distributor is oriented with the vacuum advance pointing forward to about the 12:30 o'clock position with the engine at #1 tdc and the rotor at the 1 o'clock position.
I looked under the cluster and the cable runs straight through the grommet with no bendds, therefore no slack. Someone else removed the distributor for repair so I'm not sure of the situation before it was removed. I do have one of those 90 degree adapters, but that won't help the cable length situation.
So, to replace the cable with a longer one, I'm going to have to remove the cluster to get at the connection at the tach. And I wonder about removing the grommet which also houses the speedo cable since that's the only way to get the cable head through the firewall.
Any my ideas what might be going on here?

The problem is likely one and the same. I can't tell much from your description of distributor orientation but I'd suggest someone took the gear off the shaft and put it back on wrong, throwing your distributor out of line with the tach cable. Or, your distributor is just installed in the wrong notch.
Replacing the cable with a longer one isn't the answer.
Just from memory the vacuum can pointing to 12:30 position sounds wrong. Seems like it should be pointing more to the 2:00 position or there-about, which would move the tach connection towards the cable end.
thanks guys. I'll try "clocking" the distributor clockwise a few notches. So, as long as the engine is at TDC and the rotor points to the #1 plug wire, I should be good for the startup? Maybe I can post a photo later this afternoon.

Maybe you missed the part about somebody putting the distributor gear back on the shaft 180* out from where it belongs/used to be? If they did, you'll still be wrong no matter which way you drop the distributor in.
