Five liter Olds or five liter Chevrolet?

Back in the day, we did a lot of timing chains in those Olds 307's. It was mandatory to pull the oil pans because of all the plastic debris from the gear.

The switch that goes to the brake lights is normally open.

Any reason you haven't preloaded your lifters? Sorry I can't help you on the electronic questions. I'm just learning myself.
