COMP Cams Camshaft B455 295T H-107 T Th

COMP Cams is well-known for making performance valvetrain parts that help engines breathe better and make more power. This Big Mutha' Thumpr camshaft is designed for Buick 400, 430, and 455 cubic inch V8 engines, fitting a range of vehicles like the Buick Electra, LeSabre, and Riviera from the late 60s through the mid-70s. It's a hydraulic flat tappet camshaft intended for street and strip applications, meaning it's built to perform well under demanding conditions but will have a noticeably rough idle.

To get the most out of this camshaft, your Buick V8 will need some supporting modifications. COMP Cams recommends a minimum of 9.5:1 compression, a 2800 RPM stall speed torque converter if you have an automatic transmission, and you'll also want to ensure you have a good intake system, appropriate gearing, and headers installed. These components work together to help the camshaft achieve its performance potential, especially when you're pushing the engine hard on the strip.
