I wanted to give an update. After replacing the plug wires, plugs and checking timing, I checked the rocker arms, several seemed loose, So I pulled the cam, sure enough I had wear extreme on 6 lobes, 2 were rounded off. Best thing I could figure is that the previous owner did not properly oil the new cam and lifters with a high zinc oil. I got it all back together and it is running great now. thanks for the help and I hope this thread may help someone in the future.

I use to have an old 68 Firebird with a 400 and was running an HEI and had the distributor 180 out. It started and ran around the block but when I laid in to it it all went to hell. It coughed, popped and farted all over itself but I was able to nurse it back home.
I was under the hood and hadn't figured out what the problem was so I was frustrated and did the only logical thing I could think to do in my 20 year old mind and revved the **** out of it. It backfired hard enough so that it blew my mufflers apart and peppered my legs with dirt & gravel hard enough to draw blood.

I have heard about the spark skipping around in these dizzy HEI distributors. But I have tried setting the distributor to the 0 TDC mark on the HB and then tried it 180 degrees and it will only back fire. I set it to the #5 with the HB on 0 TDC and it fires right up and runs great. Let me stress, my engine is running perfectly like this. I can smoke the tires down with my posi 9" rear end.
the timing for my engine is. 1 3 7 2 6 5 4 8 ... so the #5 is no where near the #1 on the distributor cap. No one thinks this could be the wrong harmonic balancer??? I will check #1 for TDC but my money is that TDC on the HB will line up with TDC on the #5.
