Has anyone ever tried Mac mid-length headers for this swap? I've been wondering if these will work.

most have used the mac 351w/fox swap headers. for a k-member, try either the aje lsx/fox swap k' or any 4.6/fox swap k'. if you search under mustang, notch, notchback, you should get a TON of info, but you have to read it to find it, it is there! hope that helps. oh, and don't quote me becuause i didn't build mine and i could be completely wrong.

I don't have a fox, but am wondering if the ls1 rx7 longtubes will fit. They are built to sit very close to the motor and trans.

They can always be resold if they don't work.

Also,

If they haven't already been tried, I'm sure someone that has them can take some measurements for you.

I like they way the headers hug the motor. Definately interested in seeing if they fit...

How much do those LS1 RX7 headers cost? Those look like a good alternative especially since I am going to run a motorplate and don't have to deal with the motor mounts getting in the way.

Thanks,

It's not the motor mounts that are usually the issue, it's the steering shaft. With my setup, no matter how close the front tube could've been to the block, it would not have cleared the steering shaft.

Understood, however I would rather have to modify one or two primaries to go around the steering shaft than cut the whole flanges off, reshape the primaries on the 351 headers to fit the LS1 oval flanges and then probably have to modify them even a little more than that.

I hear ya on the cutting 1-2 tubes vs swapping flanges and all that jazz. I found that many of the headers that looked like they would fit close (C5, GTO or even 1st gen camaro swap headers from hooker) were $500 and up, whereas the Pacesetters only ran me $290. And even then mine ended up as you see in the pics from the other thread because we decided to go equal-length. Heh, I can really only tell you what didn't work anyway since I'm definitely no engineer

Might sound stupid but can you use the STOCK ls1 exhaust manifolds?

Try some BBK 1 3/4" 5.0 long tubes. Cut the head flanges off and weld the LS1 head flange on. I did this as a cheap way to put long tubes on my RX7. Fits great and I would think it would work in a Stang. Cost me about $300 before coating them.

where did you buy the LS1 head flange to modify your headers.
