OK, Thanks !
It's still listed as Jack's Auto Sales & Garage, with a phone number. Unfortunately, I'm out of town right now, and don't have a cell phone(if ya'll can believe that). Hey, I'm not oldskool fur nothin.
I'll call as soon as I can. Thanks again !
Talked to Jack. He gave me the name of one guy who might be of help. I told him we'd seen him race the big wagon, with the screamin 389. He said he popped the clutch at 7500 rpm, except for the final round. When he made the final he'd put the pedal to the medal and leave about 8300-8400 rpm. Said he thought the only thing keeping it from going higher was the valve springs. It was definitely the highest winding Pontiac engine I ever heard.
