Outstanding cam utilizing an advanced profile design. When combined with Screamin' Eagle® carb/intake/air cleaner/mufflers/high compression pistons and Screamin' Eagle® heads, this cam produces a broad torque curve from 3000 RPM to 5500 RPM with a peak horsepower of an astounding 95 at 6200 RPM! This cam requires compression increases for optimum performance. (See Caution Below*) For Race Application Only.
*CAUTION: Requires use of Screamin' Eagle® Valve Spring Kit and Screamin' Eagle® Adjustable Pushrods for installation and to ensure proper clearance. Failure to comply may result in engine damage.

Note: 1340 Cams over .510” lift may require case and/or tappet guide machining for cam lobe clearance. 84-85 model’s pistons may need to be fly-cut to obtain proper clearance. Please refer to instruction sheets and service manuals for more details.
