For what it's worth, here is a link to the magazine: http://caferacermag.com/

Maybe it only applies to the quarter mile?  

Here is an excerpt from the article:
------------------
Back in the late 1970's, Reverend Jim was a hot-shot on the Deep South motorcycle drag racing scene.  Running a slammed and lowered CB750 Honda with a highly tuned single overhead cam engine, Jim, then in his thirties, had gained a reputation as both a fast man in the quarter-mile and a handy tech with the wrenches.

The winning racer had some big plans in the works during the 1978 season, plans that involved installing a rare and very expensive Goldenrod racing motor into the 1975 Honda.  The engine, featuring light-weight rods, overbore cylinders with high compression pistons and tall cams and a balanced crank, would boost Jim's performance into the realm then held only by Kawasaki's 1000cc Z1.  But technology has a way of usurping even the grandest plans; by the end of that racing season, Honda had introduced its latest CB750 motor, a new, dual-overhead cam model that, in stock trim, could outrun the costly and highly-modified racing motor that Jim had procured.
