Comp Cams CL11-243-4 - Comp Cams 'Xtreme 4x4' Hydraulic Flat Tappet Camshafts Details

*Note: In order to use these camshafts in 1965-66 396/427ci blocks, it is necessary to machine a 3/16'' wide x 7/64'' deep groove in the rear main journal of the cam to allow oil flow to the top of the engine.
Good top-end power, needs good intake, headers and gears. Use with 9.5:1 compression and 2500+ stall converter.

Big Torque Cams! Four wheel drive engines have special needs and requirements that most street performance camshafts just can't properly statisfy. Comp Cams Xtreme 4x4 cams produce tremendous off-idle torque and throttle response as well as big torque throughout the entire operating range without sacrificing necessary vacuum. We do not recommend the use of stock valve train components with these camshafts due to the aggressive lobe designs.
