I also drove it about 10 miles and it also has a miss. Got to be something wrong with the ignition but I haven't figured it out yet.

I'd still try to "hot wire" it ... 12V lead from + side of battery to the IGN terminal on HEI. That would isolate the ign system from all except the 12V source.
Don't know if this has been mentioned yet. Do you have an electonic tach connected to the HEI? If so, you may want to unplug it also in case the tach is causing an issue ... TAZ
