FTI GT40 "King of the Road" Hydraulic Roller Camshaft - (KR1)
Due to popular demand, FlowTech Induction is offering our "GT40-KR1" small block Ford custom hydraulic roller camshaft profile separately. Designed specifically for the popular GT40 cast iron cylinder head combinations. When combined with a "properly" ported Cobra, Explorer or GT40 intake and the basic driveline mods, this camshaft will melt the tires off any performance project.
This "GT40-KR1" camshaft requires aftermarket tubular headers with free flowing mufflers & exhaust system. These street/track grinds will not work with factory computers without modifications and/or professional tuning.
All our billet steel core hydraulic roller camshafts require a OEM steel distributor gear. Also recommended is a modified cam retainer plate. FTI-CR-2
