Competition Cams 12-560-4 Nitrous HP Camshaft

Fits Chevrolet GEN 1 Small Blocks including the 262, 265, 267, 283, 302, 305, 307, 327, 350 and 400. Does not fit LT1/LT4, or factory roller Small Blocks built from 1985 and newer. GM gradually added roller camshafts to 305's and 350's from the mid 80's forward. Camaros/Firebirds/Corvettes received the roller cams early, but many trucks and SUV's had flat tappet cams until the mid 90's. Remove the intake or timing cover to confirm whether the block is a factory roller or flat tappet. Does not fit the LS1, LS2, LS3 or any LS-based 4.8, 5.3, 5.7, 6.0 and 6.2. 1955-1957 Chevrolet 265 engines require a groove on the 5th cam journal for oiling.

• Wider lobe separation and added exhaust duration from base XE series help shift the power to higher rpm where it can be used in nitrous applications
• Early exhaust opening helps scavenge the extra spent gasses out from nitrous or forced induction
• Better time slips for nitrous passes at the strip
• Slight sacrifice of some torque and responsiveness to the base XE family for improved performance with nitrous oxide
• Works best with COMP Cams® roller rockers and matched valve springs
• The big question is which time slip matters more to you (normally aspirated or N2O-assisted)?
