Fitment & Compatibility
For air-cooled VW Type 1 engines. EMPI lists it as comparable to the Engle FK8 and recommends new EMPI lifters, part number 21-4300-0, with every new cam. Check lifter-to-case clearance, spring coil bind, retainer-to-guide clearance and piston-to-valve clearance at full lift before final assembly. Performance cams are not legal for sale on pollution controlled vehicles. PMB Performance can help confirm this against your build.
