The first 15 years of Pro Stock.

The early ones were 4 speeds. Not too long for the Lenco's to take over. Og, This vid was a few years ago. Mike (RIP) had one of those clutchless 5 speeds. You can hear the tires chirp between gears. (1/8 mile track only uses 4 gears)

Damn, that sucker was rippin'
