This may be out of left field but I had a similar problem when my Duster had a severe vacuum leak through the intake manifold. In my case the heads and intake had just been replaced. I think it is less likely in an engine that previously ran well...but maybe worth thinking about.

I just ordered a new Summit ignition box, MSD pickup, and MSD high vibration Blaster coil. Hopefully this will fix the problem. I guess the digital 6 plus box that I have is potted in urethane and thus not repairable.

I will check the plug wires this afternoon after I get up (working nights)

I am using IMM Indy heads with beehive springs. My lift is only about 0.57 inches and they only have about 50 quarter mile runs on them. I hope they are not giving up already!

Thanks for the replies. I may spend the $30 or so for a new pick up and see if there is any change. I also am planning to look for any obvious cam issues. The valve covers are off and the rockers look fine but I did not have time to watch each valve open and close as I rotate the engine. This...
