Joe Spinelli's '69 Boss 429 Was Originally Owned And Raced By Al Joniec (http://www.mustangmonthly.com/featuredvehicles/mump_1005_1969_ford_mustang_boss_429_pro_stock/index.html)In the late 1960s, the NHRA needed Pro Stock. Truth was, the Super Stock division that had become a stand-alone part of the NHRA's program in 1967 had problems from the start. In an effort to continue what had been the normal method of racing in categories other than Top Fuel and Top Gas, the NHRA split Super Stock into a group of classes with a handicap starting process based on vehicle weight to factor-corrected horsepower, meaning the NHRA had to determine an engine's actual power output to classify the car.
