Recommended for all around street performance, an upgrade over the dual quad Riviera cam gives 20 HP increase in most combinations. TA 1440 Stage 1 springs recommended. Stock converter and gears ok. Good idle.
Idle Quality:
Smooth Idle - just like stock
Good Idle - mild lump, but doesn’t impair driveability
Moderate Idle - nice performance sound
Fair Idle - heavy lump
Rough Idle - very lumpy race type idle
