Re: VINTAGE CHAMP CAR REPLICA BUILD

When he saw the champ car he said he was the guy who worked in the Engine Build area at Ford on the crossflow six program. He was pleased to see one being put to work.

Is there any chance he could be prodded to share any details he might have in memory? That would be wonderful!
