Keith Dorton is a world-renowned circle track engine builder who is noted for the extraordinarily successful engines that his company builds, including NASCAR winners. He's also deeply involved in many R & D projects for many of the major original equipment companies. Keith builds extraordinarily successful engines because he thoroughly understands the intricacies of engines and fuel systems; he's careful, methodical and devotes the necessary time and effort to do a job right the first time. For this reason he was approached by Holley to help develop a family of two and four-barrel racing carburetors that would have no peers. The Keith Dorton Signature Series is no ordinary line of race carburetors. These carburetors were planned in detail from the outset. Then they were carefully developed, dyno-tested and track-tested by Keith Dorton and Holley to be the epitome of circle track racing carburetors. Relying on his years of hands-on experience and technical expertise, Keith Dorton has accomplished his task in admirable fashion. Race ready out of the box, Keith's carburetors are designed for bolt-on-and-win performance.

Holley has been the undisputed leader in fuel systems for over 100 years. Holley carburetors powered every NASCAR Cup team and nearly every NHRA Pro-Stock champion for four decades. Now, Holley EFI products power these cars and are dominating the performance world. Holley products for GM's popular LS engine are dominating the LS scene as well. Holley's products also include performance fuel pumps, intake manifolds and engine dress-up products for street performance, race and marine applications. As a single solution or partnered with products from other Holley companies we can give you the edge you need over the competition!

NOTE: Due to the natural color variations of the dichromate plating process, the plating color may vary from casting to casting (within a carburetor) and from carburetor to carburetor. This is considered normal and is not a cosmetic defect. If you desire a carburetor with no color variation, please shop our black and shiny finish carburetors.
