Ok.....so 99.9% sure I rectified this issue having driven it for a few weeks without skipping a beat (watch it happen to me this afternoon!!!)

So I took all your suggestions as well with people I seek out daily to tell them what was going on. I went back and forth...one day I was sure it was a fuel issue...just to jump a few days later to the other side of the coin thinking it was no doubt it was an electrical/ignition issue. Here is what I did since adding the new plug wires.

1. I hooked up my VOM to power going into HEI. At idle I'd get 11.9 volts and when driving it it'd go as low as 10.1 volts. So...having read up online forums I came up with a few GREAT leads on solving my problem. One was do not use power/wire going to old distributor to power up HEI and two you can't give HEI's enough voltage. So....I came off my "unfused power" terminal on my fuse block, installed a 20 amp inline fuse, and ran it right to power in to HEI (next to lead coming off Tach). Started it up and had 12.9-13.2 volts constant at idle and under load. I thought FOR SURE this was it and drove it confidently for almost 3 days before it happened again and then after much disapointment I was back to go over to the "fuel" side of the coin.

2. I purchased a carb rebuild kit for my Holley 650 dbl pump & a new mechanical fuel pump. Because of limited time over the 4th of July weekend (kids and wife) I rebuilt the carb on Saturday afternoon which was LOADED with crap...and then installed fuel pump Sunday morning.

I like to do one thing at a time so as to know what the culprit was but not having the time to rip around with it after just doing the carb rebuild....I have been driving it since without the issue occuring.

So...that's it fellas. We can debate whether it was all the junk in the carb or possibly a fuel pump that was slowly getting ready to croak....I just know she's been running strong since having done everything on the ignition side of the coin....and now on the fuel side.

Hope this helps any and all.

Thanks,
Henny
