#1 Grind low compression camshaft - 1

Designed with shorter durations and greater lift to offer a wide torque range across the entire rpm range
Designed for hydraulic systems but also compatible with solid systems
Grind #1 is the low-compression version of the "A" type camshaft for 74" and 80" models.
Manufactured in the USA
On engines from '77 onwards, the camshaft, sprocket and breather valve bore diameter was modified. These components are not interchangeable with earlier models unless replaced as a set. Post-'77 gear sets are identified by a circular machined groove on the outer face of the cam gear.
For '48 - '69 Big Twin.
