Universal exhaust manifold?

I recently found an aftermarket exhaust manifold that is advertised for a SBC. The seller claims to had it installed on his 351W. The manifold does seem to have multiple bolt holes (or AIR provisions) but I am a little confused. I don't know the manf. of the it though. It this possible?

No offense, but both of you need some educating.

If indeed he has a 351W, and this "manifold" was on it, it is NOT for a SBC.

Your "time for some power" desire should be pursued via headers made for a SBC. I'd recommend you buy new stuff from a place you can trust (Summit, Jegs), so all you have to do is tell them make/model/year/engine, and they'll send you something that fits.

Well, I guess I should clarify what I saw. This was for a turbo manifold that had a T4 V1 trim on it.

You can take the rest of your comment and shove it. My question was valid. I have no idea if Ford heads and Chevy heads have similar port locations or bolt pattern. I didn't think they are, but you never know. Mail order headers will not work for my project. If they did then I would have ordered them, along with MANY other people on this board.

There are no Ford heads that have any port/bolt pattern that is similar to any Chevy head. Perhaps the ad intended to say "small block Ford", in which case the 351W makes sense.

I don't know what you're working that excludes you from using mail order headers. Specific information is often helpful in getting useful answers. If you're working on something more advanced than what I've done, then I would have expected you to know that Ford and Chevy don't share parts, however...

I know practicly nothing about Ford parts. I was under the assumption that they were not interchangable but have never read/heard such a comment. I just wanted a concrete answer.

This is the pic of what I saw:

The description was misleading and it looks like a SBC manifold... with a few more bolt? holes.

So, does that look like a SBC or SBF manfifold?

I'll take one more stab at it, since no one else did.

That appears to be a SBC exhaust manifold. It has never been on a 351W. The extra holes are for A.I.R. fittings. The "universal" part means it wasn't made for any specific application.

I'm not sure that center outlet (which is really an inlet for the other side to feed the turbo) will clear a 3rd gen crossmember, though.

You might try posting (with picture) on the power adder forum. Someone there may have more info.

Civilized I like that. Thank you.

I finally got the whole scoop from the seller. The turbo was used on his 351W and the manifold was something he had "lying around" Don't ask me why.

I would have asked on the PA board but I don't seem to have much luck getting responses over there. Granted it was a "bit of both worlds" question (in the end)

From the photo, I'll believe that.

I had no intention of being uncivilized. Sorry if it came across that way.

To run a single turbo on a V configuration, would you have to put it after a Y, or can you just "do one side"?

You can just run one bank to the turbo but it isn't advised. With the setup you see here, just bost the manifold up to the passenger side, and run the drivers side exhaust to the crossover connection. That will drive the turbo with both banks of cylinders.... like so:
