From a Chevy Dealer.
Inpossible, the engine is not designed for a distributor.
Yes.
Absolutely
It is clockwise
The cam sensor is the distributor.
It is in the back of the intake manifold, by the fire wall.
NO, It is electronic ignition.
In a 4.3 liter, about 175, in a 5.0 liter, about 210, in a 5.7 liter, about 250.
I asked that question--what is the answer
go to a shop that's your best bet
Counter clockwise to advance.......clockwise to retard
it is in the distributor
