Hamilton Cams Stage 2 Camshaft (3.9L 4BT Cummins)
The 07-C-188/220-4BT camshaft is Hamilton Cams best all-around performing 4BT cam to date, from idle to 4,200 rpm. It is also the largest drop-in cam that Hamilton Cams offers.
For it to be “drop in” on a 8V you will need 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 16V you will need no more than .018″ piston protrusion and at least .038″ valve face depth with a standard gasket. If you do not meet the minimum requirements for piston to valve clearance you can run an oversize head gasket or cut valve reliefs.
