I ran this exact combo in the early 90's. Awesome motor. 500+ runs and 20,000 miles before tear down and it still looked almost like new. I still have the reassembled short block in the garage as a backup. Ran low 11's at 4200+ with it. I wonder if we built the same motor based of the article by Tony DeFeo?
