I have not driven a car with the TF hyd roller cam but we have run several of them on the dyno and they make really nice power in the 440 to 500 inch engines. Torque peak for this 470 was down around 4600 RPM which should be great for the street. Not really a drag race camshaft but it should be a nice hot street cam. I just don't know what the idle quality is. At fast idle on the dyno this engine had 16 inches of vacuum but I don't know what it would be if the idle was 900 RPM.
