Test fitted carbs, Ram Air pan, inner fenders, and finished troubleshooting the wiring so everything now works. We left the idiot lights functional, but added an oil pressure gage with the sensor in the gallery next to the distributor.
With the Tripower and TH400, it's really tight with the kickdown switch mounted in the stock location. It looks like I'll have to set the mechanical linkage up like the '66 Olds with the slotted actuating rod going to the front carb. I'll still be able to use all factory parts, however.
