After looking at the car a little deeper today here's what I found.
The shifter cable popped out of the bracket which explains why it wouldn't go in park on the trailer.And why it wouldn't shift on the 1st and 2nd pass is my best geuss.I found the float levels low on the carb so that should explain the lean popping that was going on.I'm not sure why the floats were low because after getting the new motor in I made sure the floats were right and air mixture was adjusted.
Does this sound right?I was told 31*-32* should be all I need for timing.And the plugs are a little too cold.They are Autolite AR3933.I was told to go with Ar3934.What jet size should be about right for this motor in texas heat?
