    Question Fox Body Long Tube Headers?

    I know this has been discussed before; and after looking through the search, I wanted to ask about this in a new thread. What was the issue with fox body long tube headers in the box Panther chassis?

    Primary tubes for 1 & 5 hit frame. Same with tri-y mid lengths.

    mid length are a better option. They still need some tweaking but its not nearly as much work to make it go.

    Yes, the mid-length headers needed a lot of tweaking; as in smooshing primary tube#1 a lot to clear the x-member. Passenger side initially fit without having to do anything; but after a couple of months, the engine settled and primary# 5 now sits on the X-member. Giving some thought to raising the engine a 1/4”.

    With that said, I was looking at the Bassani long tubes and the primary# 1 tube looks to run a bit higher than my mid-lengths. And there were some complaints about the headers hanging too low on a fox body. Made me think that what doesn’t work for Fox body’s, might work for our cars. Just a thought. Unfortunately, I already went the route that I did a decade ago when buying my Doug’s Headers at a swap meet.

    Smashing the tube for clearance defeats the point. To make it work right you have to cut and tweak things for clearance. Duceandahalf (sp?) had pics of a set he re-worked for an 85 on here years ago. No smashing, but lots of cutting and tweaking to re-route the tubes as needed.

    honestly this is why i stick to boring shorties. They fit.

    I still have the BBK shorties off of the lopo in case I have real problems. Ideally, my Dad would have had me yank the engine so he could notch the X-member; then I could have run the mid-lengths without any modifications. We’ll see what happens when I get the CV running

    I'd modify headers long before I messed with structural stuff on the frame.

    My 87 had long tubes when I bought it. If they weren’t crappy I’d give them to you but in the shape they’re in would be an insult lol. It can be done but I wouldn’t want to modify them to fit. But thats just me. I’ll stick to my stock exhaust.

    This interests me.
    Neck-Deep in this 347 and the one thing I'd really like to have is headers in lieu of the BBK shorties I'm using..

    Engine masters did a header bash test and the loss was insignificant.
    Cant find it on youtube, but here it is on another site.

    I think if I were to attempt to install long tubes on a panther, I would probably try headers from a non-unibody vehicle rather than fox long tubes. I’d love to see if truck headers would need extensive modifications.
