Well, I started out in 60 with a new Impala with the 348 with 3 2 barrels, solid lifters, and 4 speed tranny. Traded in in 62 for an Impala with the 409 with 2 4barrels, 4 speed and all the goodies I could get. It ran easily in the 12s. My problem was Don Gay with his Catalina 421. He was sponsored and ruled the area where I ran. Later on I became partners with a guy with a 58 Corvette. We used a 283 that I built in my garage. It only had one carb but it ran in the 11s. That old engine was turning 9 grand going over the finish line and lasted a year. It would lift the front wheels in first and second gears. Found out it had a 5:57 rear gear. Great times!!
