Denny---I think that your idea has merit, in terms of an idler pully to increase wrap on the waterpump pulley. I actually have more room for one between the waterpump pulley and the crank pulley, as you can see in the attached picture, plus there are 2 tapped holes in the block just to the right of the crank pulley that would form a good mounting point for an idler bracket and also be a bit more pleasing to the eye, as I plan on running no hood sides. Henry Rifle----Your set-up appears to have about the same amount of wrap as mine. Have you actually driven this car, or is it still in the building stage? The chassis and engine show some very skilled workmanship.
