I have the same hedders. Look at the center of the collector where the pipes go into it. Make sure all the pipes are fully welded. Mine were not and I had a large exhaust leak on the driver side. One tube was just tack welded.
Everything is all hooked back up accept the hei. Still waiting on parts from Summit, should be here tomarrow. Had the exhaust hooked up yesturday, they did a nice job but the pipe wasn't aluminized like I thought it was gonna be.
Lookin' good motorhead!! Ain't it fun doin' all that wrenchin' and cleaning, just to get it dirty again? I got my '80 all back together and fired it up today! But the float was stuck of course its that stupid carter BBD So I picked up a carb kit tonite, along with some dex II for the T-4, I put 80-90w in it when I tore down, gotta fix that. Anyway it looks like I'll get it muddy this weekend!! Minus the winch and both bumpers, but hey, you don't need those right away right? Good luck w/the hei. I'll hopefully have more pics posted by this weekend!
Just got it fired up! Some how I had the distributer 180 off. Its a little louder than I would like but it sounds good. I also burnt one of my new moroso plug wires on the header so I need to deal with that. The POR 20 I put on the headers is already flaking , so don't waste your money on that crap! Should have just bought the coated headers, but I was poor back then. lol
bummer i had that happen to me once, painted the headers all pretty like. fired her up and with in one minute all he!! broke loose, smoke everywhere. on this build i'm deffently going with thermal and ceramic coating. when you say loud how loud, car alarm loud. what kind of muffler did you run. i like em loud, nothing like a v 8 with headers. except well you know !!!!
Its not real loud, as it turns out I like the sound. When I first started it the jeep was between my truck and boat, so it sounded louder. I don't remember what mufflers are on there, but they are a flow through design. The pipe is 2 1/4" all the way back. Along with the new cam it sounds like a 70s muscle car!
Sounds good motorhead. I just gave mine the first run today, about 150 miles round trip, to the cabin and back. now I fid out I need a water pump and a lower balljoint And the speedo is way off, so I just used my GPS. 45 on the speedo is 65mph on the hi-way, so that'll work. The rebuilt carb works great, did that little tube cleanout I saw on a link for the 258 w/carter bbd. Those babies were plugged!! Now she idles great and runs great! I didn't get it muddy yet, but I will...I will...
