Buick 400 430 460 Rollmaster Double Roller Timing Set (CS7031)

All Rollmaster Red Label timing sets are produced using billet steel for both the crank and camshaft sprockets. Red label sets come with 9-crankshaft keyway sprockets allowing more adjustment for dialing in the cam. Crankshaft sprocket keyways are in 2° increments always; unless otherwise noted. The relationship from crank keyway to camshaft sprocket timing is 2:1 meaning that the amount of advance or retard at the camshaft is in one degree increments, i.e. 1°, 2°, 3° or 4°. Multiple keyways are a solid fixture and do not tend to move or work lose like offset dowels, thus providing a positive locking of the cam timing to what ever position is desired.

Rollmaster timing sets are light-weight and stronger than any other timing set available due to the weight savings of billet steel and CNC machinery. No additional machining is required to fit these sets or the need for offset bushings or drilling of cam gears. All Red Label timing sets come standard with Rollmasterʼs own premium grade Iwis full roller timing chain.
