Lunati representatives will also discuss options for custom grinds, including Chrysler applications.

Some of the applications offer complete kits with cam, lifters, valve springs, retainers, locks and a timing set. For each application there are hot, hotter and hottest grind options to give builders more flexibility in matching the cam to the engine’s compression ratio and head flow. The cams are offered in hydraulic flat-tappet and hydraulic roller versions, including retro-fit hydraulic roller kits. Lunati set the intake centerline at 104 degrees for the entire series, which covers the traditional Ford and Chevy small-blocks along with the Chevy big-block. “The intake closing is more tucked in for the street RPM.” “On the design, the Bootlegger is more like a race cam on the exhaust opening with just a little less overlap to allow some street manners,” explains Lunati engineer David Chamberlain. Lunati, however, took a radically different approach. The introduction of Lunati’s new Bootlegger hydraulic series – with its wicked 108-degree lobe-separation angle, fast opening profile and plenty of area under the lift curve – will serve only to fuel the flames on this heated bench-racing topic.Īccording to legend, the first 3/4 cam was developed by Ed Winfield when he matched the intake lobe from a full race cam with the exhaust lobe from his 1/2-race series – hence the 3/4 designation that has evolved into hot rod vernacular for a hot street cam. Ever since hot rodders in the ‘50s started swapping “3/4-race cams” into their engines, the search for the ultimate street cam has been an ongoing and highly debatable issue.
