jeepcj

corveeper, I posted a couple pics I found the other day of the trans if you want to take a look. the pics were of the floor pans taken about a year ago but the trans shows up pretty well in it. will some pics up soon of the whole jeep soon.

That’s why I don’t like horsepower guestimates. They’re notoriously over guestimated and the numbers typically get more ridiculous with the number of people being told and/or the amount of alcohol being consumed.
You could have a stock intake manifold, they actually flowed pretty well but if I recall correctly they’re cast iron. When you get the chance see if a magnet will stick to it.
The exhaust actually sounds pretty good, you’ll get good flow out of that setup. After talking to an online friend that’s a shop owner and has run literally hundreds of cars on his chassis dyno, he says if you’re running a Flow Master you might as well be running a cheap ole Turbo muffler. He says the dyno doesn’t care, that Flow Master my claim better flow than other chambered mufflers but it doesn’t show up on the dyno.
Spark plug wires make sense, the way you describe it sounded like it wasn’t quite hitting right on all cylinders for some reason.

Sorry jeepcj but I am not familiar with wrangler steering.
