Andrews EV23 Cam for 1984-1999 Harley Evolution Big Twin

Product Description

Andrews EV23 Camshaft for Harley Evolution Big Twin

Increase low-end and midrange torque in your Harley-Davidson Evolution Big Twin with the Andrews EV23 Camshaft. Designed as a bolt-in street cam for stock-compression 80ci engines, the EV23 provides crisp throttle response and strong pulling power while maintaining excellent everyday rideability.

The Andrews EV23 is especially well suited for heavier Touring models and high-geared motorcycles where strong usable torque is more important than an aggressive high-rpm powerband. With .498" intake and exhaust lift, the EV23 works with stock valve springs and hydraulic lifters on compatible applications and can be used with either carbureted or fuel-injected Evolution engines.
