Lunati's Camaro, The Dixie Devil, went to the final of Funny Car Eliminator at Indianapolis in 1967 (the first time the class was run there), where Lunati lost to Doug Thorley'ss "Doug's Headers" Corvair.[4] (The Camaro was wrecked a short time later.[4] )
Lunati also formed the cam-grinding company, Lunati Cams, purchased by Holly Performance Holley in the mid 1990's. Lunati Cams, now Lunati Power, was sold again in late 2007 to an exclusive ownership group made up of industry and racing veterans.
