what to use to electric shift a turbo 400

[Dave Goob Cook]

The ACD is the Cadillac of 3-speed auto shifters for a Quarter Stick, but all of the setups require you to render the lock gates inoperative.

Not sure if the combination shift controller from Biondo is legal to hook up to the tach output of your ignition or not.....I'd say if there is a timer in it, it would fall into the same category as the Mega-Box in that regard.
No tach or other ignition input to the Mega-Box is allowed.
Long STUPID story on that witch hunt.

Peter could tell you with a phone call....
