thanks to Virgil & sue, The speedometer problem will be addressed. Now, I am having trouble overheating. After getting the car on the road, it would overheat at freeway speeds; but not driving around side streets. I checked the timing advance. I found it to advance to about 32 degrees BTDC at high RPM. I put a stronger spring in the distributor and that fixed the normal driving at highway speeds. Today, I took it out to where there is a good size grade and it overheated going up the grade. I had the radiator cleaned out when I first got the car. My question now is does anyone know what the advance curve should be on the 53 Mercury with the original 8ba engine?
