Is there any one that knows anything about them or some one that services them. We just did a motor (426 max wedge w/cross ram) that sat for over 20 years, customer states it runs but runs rich, weak spark & #s 1 & 7 not firing.
Send a PM to GMC Bubba. He rebuilt mine a few weeks ago. He has all the old distributor machines and equipment to test it.
