I saw over on fordification where a guy said 71-73 mustang headers fit in his truck with a 400. So if that's the case, they should fit with the Cleveland too.

anybody know anything about this?

 

you would think, since there is more room in a trucks engine bay, yes, BUT idk and it always seems "they" throw just enough something in, where it won't work. If it does lets us know. More parts options is always good. (big thumbs ups!)

 

But, what was his truck? What year, what transmission, did it have 4wd, etc?

 

It was a 78 f150 4x4 with a 4spd I think. Said the mustang headers dropped in no problem.

I was looking at them online, and looking at my truck, and I'm pretty sure they will. I'll buy them and see. If they do great! If not and they aren't even close, I can return them and get my money back.

 

Let us know, please.

 

I sure will. I know that there have been several of us with Cleveland's struggling to find proper headers.

 

Just because those fit a 400 application doesn't mean those will fit a 351C app. The 400 raises the header flange up ~3/4" and out ~3/4". This puts the header closer to the floor pan and on the truck it will raise the primaries up and away from the frame. With a 351C, the primaries will be lower and closer to the block so these may hit the frame. Try to pick up a set of used/trashed headers from Craigs list or a swap meet, then you won't be out of a bunch of cash should those not fit.

 

hows it going to hit the frame if the frame is on the outside of the headers and if a trucks frame is wider than a car frame?

I will measure the mustangs frame width and the trucks frame width tomorrow when I have some light.

 

is that driver side header hitting the oil pan?

 

Yeah those 400 headers hang down WAY too low for my liking. I'm glad I didn't buy any of those.

NO, the headers clear the oil pan plenty, that is shown in the pictures. The headers hang only about a 1/2 lower,(A squared plus B squared equals C squared). The deck on the block is 1 inch lower, at a angle. And if a 1/2 to 3/4 lower header doesn't fit, neither will the proper header, when you hit a speed bump! NOW, will they avoid all the other stuff? I would wager money they would.

 

I measured the 72 mach1 and the 78 f150 ranger. The mach1 was about 25 inches between the frame rails and 27 for the truck frame rails. So you have a extra inch on each side over the mustang. Yes the mach came with a 351C and the f150 came with a 400. (measured behind motor mounts where the headers go)

 

Cool
I ordered them from jegs tonight so they should ship out tomorrow. Be here by Thursday or Friday. I'll start working on it when they show up.
