I'm going to try a post here because, well its Mustang related?

When I picked out a set of headers, I got a set for a Mustang instead of the F-100 because its a 351-C 2bbl. I found a nice set of Hedmans, slightly used, for a 351-C 2bbl that actually came out of a Mustang. I know Hedman is not top shelf, but this truck is developing a need for an exhaust system, and unfortunately, there is no such thing. And I sure don't want to get into an ongoing debate with some know-nothing parts store "boy" kid who will insist on telling this lady there is "nothing we can do."

I figured I'd start with the manifolds and work back. Since the headers came off a 'Stang with the very same motor, I'm assuming the starter clearence is not going to be an issue. These are the regular length headers (not shorties). But now I have a real dumb question...

Ummm, that ends the Mustang 351 piece of the truck, but what about the cab and 8' bed? I'm really kind of puzzled here because I don't really know how to set up the rest of the exhaust system to fit the rest of the F-100 . I'm guessing the F-100 system probably won't bolt to Mustang power. The stock exhaust would be single, and built for a 360 2bbl, but I want duals anyhow. And the duals for a 360-2V fit into a different set of Hedmans. So I am stuck on what to do next.

I can do without "sound" effects, because this is a daily driver and I get headaches already, and I will also be doing some interstate travel and hauling, and towing as well. I don't want to be bait for the Smokies either. But I want the pipes and mufflers to be wide enough to give me as much extra horses as I can get without running into backflow problems. I don't have a "cash" hose where the stuff keeps pouring out from, but I do want to do it right the first time. I also would like to enjoy some of that 'Stang hot rod performance, but also be able to have this vehicle act like a real truck when it needs to.

So if you all will be kind enough, please give me some suggestions for a workable system such as pipe size, reducers, quieter mufflers, and how far back I should run this thing...its got a long way to go too! And also how to go about doing it. They had to put two driveshafts on the thing to get back to the pumpkin! I mean its way way way back there!

thanx a lot

the problem is that in a truck, the engine sits higher, so she is right, there is nothing that you can do short ov searching for headers that will work or having them custom made

[Kaylah]

Maybe I'm mixed up.

I have the headers...I got them used. I was wondering what I need to hook up to them after I put them on. It was just a "hypothetical conversation" I could picture having with the parts store kid.

But you are right again, after crawling under there a few minutes ago, it does look a little tall. What do you think might gum the works when I try to bolt them up?

[Twister]

the headers are not long enough to clear the floor

[Kaylah]

You say that with so much confidence...is there any hope we can make this work (sob, sob), or is it overl?

[Twister]

I had a 67 F250 with a 428, the only thing that I got to work was a set of '63 406 tri-power manifolds

Kaylah,
See if anyone sells shorties for the motor. That way, you will not need to worry about clearing fram or floor and then just have a shop make a dual exhaust setup from the headers back.

I still havn't tried the pony headers yet, I have some brakes to install and the power steering to fix. I might reluctantly re-sell those headers and opt for the shorties. But I hate to get rid of something I haven't even tried yet...guess I still have time to ponder. Thanks for the tips.
