Sure, a race-compression 542ci engine could produce 800+ horsepower, but what we wanted was street reliability and torque. Opening the Lunati catalog to camshafts, Ken chose Lunati's hydraulic PN 33706. Technically, it has the look of an MP Purple Shaft cam with a generous 110-degree centerline. Specs are .507/.534-inch lift, intake and exhaust, respectively, with an advertised duration of 285-degrees on the intake and 295-degrees on the exhaust. Duration at .0500-inch lift is 235/245, intake and exhaust, respectively. Ken chose to install the cam 3-degrees advanced, reducing the centerline to 107-degrees. For those of you with 383s, 400s, and 440s who think this cam is a bit too aggressive, remember, our displacement is 542ci. Ken says, "With that kind of displacement, you don't even hear the cam at idle."

A Lunati 3-position cam chain and sprocket set is used as a Roller thrust button to reduce friction. Here, Ken readies the thrust button for installation with a liberal coating of lithium grease for startup and break-in. No oil is squirted to this location.
