I also want to say that the Vehicle came with the # 866 Cam, I think that is the # and it is the 1956 Tri-power one that I loved. Going to this 041 Cam is new, for when I put it in this Vehicle, shortly after I destroyed the Trans. I have yet to get used to this 041 Cam yet. With the passing gear and downshift system now working, the passing systems working again, seems to make this new Cam more enjoyable. It is not bad; I will let you know after I put the motor together and test and tune for a while.

The "Gear Vendors" is an overdrive made to reduce the overall drive ratio from 1:1 to 1:0.78, a 22% reduction in your final drive ratio. This reduces your engine's cruise RPM same as reducing your rear axle by 22% (from 4.11:1 to 3.20 for example). To the best of my knowledge, its intended used is as a final drive overdrive, not a high-low gear-splitter like you might find in a semi-tractor, though I guess you could use it that way to turn a wide-ratio 4-speed transmission into an eight speed. I don't see how you would gain anything switching the overdrive on and off after every gear change to gain the additional ratios.
Sorry for the detour, go rebuild your motor.
