Depending on how close they are maybe not. I noticed tonite my drivers side is actually touching the floor, but just barely. I'm going to try a little leverage persuasion to get it to sit down lower a tad, and if not the yeah, a light hammer on the floor never hurt anyone, and not in the amount that I'll need.

Shoot, years ago I had a '70 Chevelle that I had lowered by cutting a loop out of the coils and my headers wound up flat on the bottom (touched the pavement a few times)..... I believe they were Blackjacks.

What do you mean you won't test fit them on your car?!? What kind of service are you offering here?

Im actually really impressed at how tight these tuck under the car. If you are eye level with the bottom of the car you cant see them at all. I don't see any scraping issues at all in my future.

Just some additional on this. I purchased some SS 2v headers to do this. I just got some no name ones. They will not fit without smacking tge floor on the drivers side. Since the rear bolt on the head is still about 1" off, I cant imagine how much I would have to beat the piss outta the floor. Also, the #1 tube rubs the body chanel (not sure what you would call it) or the pare the subframe bolts in to.

Just FYI. If they would have fit at the flooe like these, I would have run them, but not knowing how much I had to bash the floor was too much unknown to do this.

SWS

Soon to have some MHS parts, cams, 'luminum block, lower compression, ported heads, autorotor, and need to make long tubes. I have almost all the stuff and need some #42-50s a bypass valve, and maybe a few other things.

Pypes brand? I know they make lower priced SS longtubes and I believe they tuck up further on Mustangs than Macs.

I think the key to finding good headers for these cars is to find which headers have ground clearance issues on Mustangs

Not sure on the brand. They are quality sis though. I will be trying to make them fit on the sc shell after I get my lx and bronco finished this year.

Sorry to dredge up an old thread, but coming from having a 1999 Mustang, there's a suspension company that does great things with the Mustangs, and one of their parts is an extendable steering shaft.

http://www.maximummotorsports.com/St...tang-P460.aspx

Would this help in installing headers in the Thunderbird? Is it close enough in dimension to work?

You would need something to support that shaft at the firewall like the mustangs have. Also, that shaft linked won't work with the MN12 steering rack, Mustangs have a triangle coupler and the Thunderbird uses a splined section

Thanks. So it's basically modify the headers or modify the shaft as described elsewhere?

Also, was trying to find steering shafts on RockAuto, and I can't find them for either Mustang or Thunderbird. Are they called something else other than Steering Shaft?

I no longer have to pass through DEQ in Oregon so I'm thinking about redoing my exhaust and putting Purple Hornies on and getting rid of the cat and three mufflers. Any suggestions?

They probably don't sell them, the only part that can really wear out would be the rubber rag joint that couples the rack and shaft together.

You wouldn't be able to use the Mustang shaft anyway, it's got a different coupler at the rack and the design itself isn't easily adaptable(It's not D shaped like ours and aftermarket type shafts are). The best bet for modifying the shaft would be to duplicate the routing of the Mustang's shaft, rather than the shaft itself. Most here route an aftermarket shaft out of the way to the frame rail with an eylet bearing, which works fine on 5.0s, but the width of the 4.6 really would necessitate running the shaft between primaries as it does on Mustangs, so some sort of firewall support would be necessary.

That really would be the best option given the fact that people take too long to make custom-made long tubes

How much is SHM asking for that set?

If I had the money, I'd buy them and take them to a reputable header company to have them replicated so we would have a legitimate long tube header option.

You have to be careful with stainless steel headers. They normally require backside protection against the atmosphere during welding because they oxidize severely in the presence of oxygen.

I should have a nice little treat for MN12ers very soon......






.....and they will come in many flavors.

Ha! If I could afford a cnc bender, I'd already have one lol. now you're dreaming. Lets all be happy I'm even doing this There's other ways to achieve consistency. Remember, I am not an exhaust shop. Just a one-man army going against the grain armed with just a couple nifty tools, and a nice collection of jumbo-sized neurons.
