Pontiac OHC & Sprint 6 Performance
It’s important to note that, while they all had the same overhead cam design, only the performance variants of the Pontiac OHC inline sixes got the “Sprint” name.

Base-trim OHC sixes were equipped with a single one-barrel carburetor and made around 130 horsepower. Sprint sixes benefitted from a hotter cam, Rochester Quadrajet, and a few other enhancements to push engine output well north of 200 horsepower.

In top fighting trim under the hood of a 1967 Firebird, the Sprint 6 made 215 hp. For comparison, the Firebird’s base 326 V8 was making 250 hp that same year. At its peak, the 1969 Sprint 6 topped out at 230 hp.

Famed tuning shop Royal Pontiac even offered a hop-up kit for the Sprint motors and, when tested on the drag strip, that extra performance could easily put you into the 14s.
