Make sure your firing order is correct and that the distributor is getting a good ground. If it backfire while you are turning the distributor, the ground would be the first thing I would suspect. On my 84 when I converted to DSII, I had to run a wire from the ground lead on the module to the negative post on the battery to make it work right.

The ground is in the distributor. Study the schematics, get someone to teach you how to read them if necessary.
