Something's not quite right.

The distributor foot should be set near the middle of the adjustment slot when base timing is set to 5*.... that's not exact, but where I've found mine to be. When you set base timing, did you ground the wire that deadends under the wiper motor?

If you installed new plug wires, did you notice that #1 and #4 cap towers are out of numeric sequence on the circular pattern?

You might want to check all of the vacuum lines and the EGR system.
