Application Summary

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.

Additional Application Notes
• In 1987, GM began using hydraulic roller camshafts in Chevrolet Small Block V8's. Before ordering this camshaft, verify that your engine has a flat tappet camshaft. If your engine features a roller camshaft, look at our "08-" camshafts or "07-" camshafts if equipped with an LT1/LT4.

If your engine features a roller camshaft, look at our "08-" camshafts or "07-" camshafts if equipped with an LT1/LT4. From 1985-1998 Chevrolet introduced the factory roller Small Block into GM cars and trucks. Verify whether or not your vehicle came with a factory roller camshaft. If your vehicle was equipped with a roller camshaft, look to our camshafts and kits that start with "08-".

Camshaft Kits, Nitrous HP Cam and Lifter Kits, Hydraulic Flat Tappet, Advertised Duration 256/268, Lift 0.434/0.464, Chevy, GMC, ISO, Small Block, Kit

COMP Cams Nitrous HP cam and lifter kits are designed to work with your nitrous system to get more power from your engine. The unique intake cam lobes allow your engine cylinders to fill better for more complete combustion. While, the exhaust lobes are spread to decrease overlap and ensure maximum scavenging of your combustion chamber. The bottom line is an increased power boost from your nitrous system, without any loss of throttle response or torque in street applications.
