Mechanikal problem is Solved, the fuel pump Stops Working some times, i put out the pump, and see the brushes was broken.
I put an other from a 94 Trans Sport in.
Now engine starts and run. I would start tuning know,
have anybody an idear for a good Initial Spark Timing for the Vortec Block Originaly in ANLU is set to 0°Distributor set also to TDC?
Original base Timing is set to 20° Advanced?

I Think i should advance Distributor Base Timing becouse in Advancing it will increase over 40° so the Rotor is nearly in the middle betwen two spark Plugs, i think its a little dangarus in case of firing the wrong Zylinder?
