The COMP Cams C43 266H-R12 hydraulic roller cam fits '87–'94 GM 4.3L/262 V6 non-balance-shaft engines. It’s tuned for good low-end and mid-range power and works with throttle body and sequential port injection when paired with an aftermarket chip. Adjustable valvetrain is required; the profile supports improved everyday drivability and mid-range response in the listed engines.
