1989-2018 Cummins 188/220 Hot Street/Strip Camshaft

This Hamilton Cam has outperformed all other cams that Hamilton has tested it against to date, from idle to 4,200 RPM. This Cam is the largest drop-in cam that Hamilton offers.

For "drop-in" on a 12V, it is required no more than .018" piston protrusion and at least .055" valve face depth with a standard head gasket and a 99 intake centerline. On a 24V you will require no more than .018" piston protrusion and at least .038" valve face depth with a standard gasket. You can still run an oversize head gasket or cut valve reliefs if you do not meet the requirements for the piston to valve clearance.
