The 6-volt alternator was invented in 1985 and went thru two years of testing before it got a part number in 1989.Well over ten thousand have been sold to customers in all 50 states, all of the provinces of Canada, and 23 foreign countries.

McGraw TestimonialRandy...the books I bought on “Gas-Oil” and “Hot Start” are priceless and have saved me a lot of headaches...I converted my entire ignition to copper ( most particularly the dist cap ) & the performance improvement is unbelievable in a 66 yr old stock flathead v8. Also, switched oil brands, added zddp and the engine is so quiet its hard to tell at a distance if its running its so quiet.

You did a great service to the antique car crowd and I can't say enough to compliment you on the value of these books. My Rundle library is among the most valuable tools in my shop. Well done ...you are the man ! Buddy

The Great Race...How It Works

How the Great Race Works

The Great Race is a timed / distance rally for antique vehicles. The teams consist of a driver and a navigator who together must follow a specific set of instructions that give them a specified route to be driven (each day for nine days) at a specified speed (both of which will change a dozen times an hour) and all without the use of the vehicle’s factory speedometer, or odometer.


To be sure they are on time (there is a penalty for being either early or late) the teams are clocked at various hidden checkpoints, where their driving accuracy is measured down to 100th of a second. Any mechanical breakdowns during the day must be fixed with no outside help… Read more
