So I took my car on my second run today cruising around. About 15 minutes in it backfired a couple times through the exhaust. I fouled a set 3 days ago as well. I think I'm running pretty rich. Also, the car ran great 2 days ago on manifold vacuum and about 24 degrees initial advance. I switch it to ported for some reason.

Also, I hooked up my timing light tonight when I got home to plug wire #1 and it didn't even flash, I'm sure it was hooked up to the battery. I have a 650 Holley DP with 71/76 jetting in it now, stock specs. Can anyone shed some light on to what I do next?

 

Go through the procedures outlined in here.

I went through those procedures. It ran great yesterday and part of today. I have about .040 of the tranfer slot on the primaries showing, and a hair of the secondaries showing. The only thing I did today was run ported vacuum vs manifold. I had it on manifold last time and it ran pretty good.

 

Pulled all the plugs... I'm running NGK V-Power 5674-7 Plugs. I have two different types of wires on my car, 3 or 4 accell 8.8's and 4-5 accell 8 mm.
I found out that cylinders 1,2,3,4 are rich and cylinders 5,6,7,8 are really lean. Its quite a difference.

What is going on here?

 

You made two identical threads?
The annoying thing about that is that you'll usually get conflicting answers in different threads when users can't bounce ideas off each other in a single thread. A single thread usually gets you to a good answer quicker.
Anyway, the tech/general engine forum is more widely used, might as well stick here.

What do the plugs look like?
