A friend of mine just bought a '69 vette, 350/350hp 4 spd. The starter s**t the bed. So the parts guy talked him into a mini high torque starter.
The old starter has terminals "R" and "S" on the solenoid with wires connecting to both.
The problem is the new starter only has one terminal. He connected both wires to the one terminal. (As suggested by a mechanic) The car will start but die immediately.
Any suggestions on how to properly remedy this wiring issue.

Only one small wire should connected to the starter. It is the one that is energized when the ignition switch in the start position. The other wire should be taped off (insulated so it won't short when the car is on, due to backfeeding from the coil.)
If it dies after it starts there may be a wiring issue with the car. The coil should get about 9V when the key is in the "on" position. (12V dropped by the special resistance built into the wiring harness). To check you need to disconnect the wires going to the coil (+ terminal) and see if one is energized when the key is on. The other wire that will not be active with the mini starter is the one which supplied 12V when the starter is being driven.
Older Chevys use 2 ways to power the coil. Upon cranking, full 12v. is supplied, bypassing the resistance wire to the coil. After releasing the ign. key to the run position, the coil is powered thru the resistance wire, which I believe comes up from the starter "run" lead. This is the outside terminal. You don't have one on the new starter. I think you will have to run a new ignition wire from the ignition switch if you will use the mini-starter.
