I am having problems. At low rpms I have a stumble and at WOT it pulls, but it doesnt even break the tires loose from a roll in 1st! Almost like I'm running oon 7 cylinders. Feels weaker then my previous setup. I dunno. She backfires to, loud! I adjusted the rockers on the dr's side while running but the backfires got worse (even though rockers are quiter). Maybe I got 2 wires crossed? I did new Taylor wires and NGK plugs (TR6's)

 

double check your wires make sure they are not burnt on a header. sounds like 7 cyl like you said definitely. also check plugs are not cracked,,, I cracked my #1 NGK think I over tightened it but it was fouled.

 

I hate hunting out crap like that. Takes for ever.

 

I had a swapped plug wire that did the exact same thing.

 

Tomorrow I will check the wires. Its what I figured.

 

Maybe you cracked a spark plug Just wiggle em all with your fingers and you can rule that one out. I feel your pain though, diagnosis of the stumble is torture. Glad you finally got it together.

You'll feel stupid but it's the cheapest repair ever.

 

Brent, your exhaust sounds badazz! Glad it all worked out for ya. Shoot me some pics when you got time.
