Default Backfiring after header and side pipe install

It’s only happening on the drivers side and it’s VERY LOUD..About every 15 seconds or so..this is happening at idle as I haven’t driven it yet due to this..I did remove all the plugs and wires from that side because of the tight clearances..could it possibly be a crossed plug wire?if so does anybody have a firing order with distributor pic?..TIA

Yes, a crossed plug wire is a real possibility. Ask me how I know. I would check that first, Symptoms are a very loud backfire every few seconds.

Sorry I didn’t specify the year on this post..I guess I was thinking to myself that it was a continuation of my previous header/side pipe post
