I couldn't figuire out how to reshape the front quarter panels to direct air around the front tires and although I bought some conveyor belt to make the front air dam, I moved on to something more exciting and easy.
This weeked I replaced the distributor and coil. The distributor is a modified unit from a 2.8 liter GM 60 degree V-6. The total advance is 71 degrees with initial, full mechanical and full vacuum. It runs better with steadier timing and less hesitation. The engine is worn-out, but a spare is now being rebuilt. I will find out in two more days how the gas mileage is doing after my first tank of gas.
I hope to report back soon!
