I'm not too sure that some of what was said in that interview was totally correct. What about Rex White? Jr. made no mention of Rex's motors yet Rex is the one that did all the testing of that motor at the GM test track in AZ.
I have great admiration for Jr. but Rex got the shaft by Chevrolet. He was the first to get cut off when they introduced the racing band yet he did all the testing. Jr. came to AZ. but refused to drive the car because he said the track wasn't safe. In Rex's book he said he agreed that the track wasn't safe but he was too broke to augue.
