Verify the plug wires in relation to tdc by removing the #1 spark plug ,And distributor cap.plug the hole with a finger,slowly turn the engine over in the direction of rotation until you feel air pushing your finger out. This will put you close to tdc.Now continue to turn until your timing marks align.This is tdc on the compression stroke.Check that the rotor is indeed pointing to #1 wire on the distributor cap.If its not correct this by reinstalling plug wires in their proper order starting with #1. The rotor should be pointing to #1 and towards the front of the engine.
