It used to be a lot harder to make junk parts go fast but we had fun doing it. Tracks are ten times better, tires are 100 times better, state of art back in the early 1980’s was super stock springs. Not many could afford to run custom pistons or the high cost of after market rods. I was super proud of running 9.82 with a .030 440 with TRW pistons, stock rods, and 906 cast iron heads on super stock springs. After 3-4 years of Racing 2-3 times a week I would throw the stock cranks on the scrap pile as everyone I had magnifluxed were cracked. A lot simpler times now.
