EARLY ROCKERS

SERIES II, 1977

The original Series I rockers of 1973 were essentially unchanged when the Series II rockers were made 4 years later. The only difference was that they incorporated Torrington Needle bearings, where the Series I used a bronze bearing to work with the Ford .700" diameter NASCAR shaft. Only 5 sets were ever made; and most of these were used solely on Jim's own BOSS engines. Although it was 4 years after the first Series 1 rockers were made before the Series II came out, they were in the pipeline long before that, so there was no urgency to make more of the Series I rockers.

CLICK PHOTO FOR  SERIES III The 1977 Series II BOSS rockers were machined from solid 7075-T6 Billet Aluminum and fitted with Torrington needle bearings. Specially made shafts that copied the NASCAR design, but incorporated a 5/8" diameter were used in lieu to the .700" NASCAR dimension. Original NASCAR stands were retained and modified to accommodate. Precision ground steel plates nearly 1/4" thick were made to elevate the rocker as needed to establish MID-LIFT geometry, first developed on the Series I model in 1973. Little emphasis on pretty, shiny anodized surfaces was used, but they were light, strong and safely allowed the engine up to 9,300 rpm, an unheard of value for a big block in 1977. Repeated NHRA World Champion Bob Glidden contracted several sets in 1979 when he switched from the 351 to the BOSS 429.

By 1980 or '81, Jesel came out with his straight beam version of a rocker for the BOSS engine and used the same bottom side ball mill lightening copied from Miller. His early pieces added a second ball mill plunge on the back side of the shaft bore, which proved fatal. That step was dropped.
