How to Choose a Camshaft
Would you believe that one of these cams could provide an extra 200 hp to your combination? It’s true. Actually, the truth is that the installation of a stock cam will cost you as much as 200 hp.

While several different rod builders have created limited-production vehicles, few handled every aspect of the construction in-house, mainly because they thought it best to team up with other craftsmen to create certain aspects of their cars. While this takes nothing away from the quality or beauty of the cars they created, it does say a good deal about SAR. By keeping every aspect of the construction process in-house, SAR has been able to maintain personally set tolerances and control the design theme at every juncture, yet still build each car as if it were the only one. And because each of the Double Dozens is offered simply as a “roller,” the final results of each still depend heavily on the imagination, talent and individuality of their owners. In the end, each of these cars will be special in its own right, and we’ll be showing them to you in the months and years to come.
