There is a nice article in Popular Hot Rodding about VP fuels for street and racing. VP was started here in San Antonio by a friend, Steve Burns. When first starting out, he would bring us 10 gallons of his latest blends and tell us to go 4 jet sizes and start there. His fuel was always better than anything we could buy. Car was faster and easer on parts. That was the now famous C 12
Four sizes up or down?
