right here in the engine swap section, you can expand to see all threads by selecting the options at the bottom of the page.  As it is now, this page loads with only a few threads by default.  just click on the option that lets you see all threads or atleast all threads in the past year. 

there are several 351w swaps posted.

I had MAC shorty headers on my '87 Sport and they rusted out in less than two years. The seams in the tubes split and I ended up having to install stock Mustang shorties to get through safety inspection (any exhaust leak will fail). I was quite disgusted...

oh really?  you must have some demented love affair with thier dumb ass  design.  i had to pinch off the tubing in order to go with a decent bolt rather then those stupid ass 10mm bolt heads they recommend.

and headman does not like to use good quality paint either,,, it burns off on the first few passes to the grocery store.  "high temp heat treated paint" my ass.



i had no problem with the  on either of them. and as for the paint, i wouldn't know.. i sand blasted mine and used VHR header paint or whatever it's called. problem solved

I have 351W with T5 in 88 TC. I am using BBK ceramic coat Mustang swap headers for approximately 5 years now with no problem from leaks or fit. It is a PITA to get them in place as steering column shaft goes through the pipes between 7 & 8, I think.
