Split 6 outlets

I've seen some 6 split exhaust manifolds here with what looks to be cast outlets just wondering where I can get some.

 

when we did it we sawed up another exhaust manifold to get what was needed.

 

Here's another tip for manifold splitting--if you ever run across an old step van that's Chevy six powered, look under the engine cover. I found a cast iron offset carb adapter on one that, when sawed in half, gives you two outlets that are the exact same size as the stock outlet on a 235.

 

On my Stude flathead 6, I found another exhaust manifold, took the two of them, cut them up and welded the 90's and flanges, and was all set. I got the idea from many others who have done it on Chevys and Ford 300's (truck motor).

 

Kool tips.

 

You didn't say what engine. The late Ford 300-sixes with fuel injection came with "split" manifolds, which a lot of rebuilders like better than headers and a lot better than the older factory manifold. I also once saw some different, much earlier, "split" (by which I mean separate manifolds for 1-2-3 and 4-5-6) cast iron manifolds for the 240/300, which reportedly came on some late '60s Fairlanes.

 

back in the old days used 1 1/2 in pipe and 2 in flex tube and that must have been cheep if I could afford it, but it hit the threttle rod and kept sliding down , oh well was young and dumm then

 

Or if you want to buy some theres' Langdon for Chevys and some Mopars

In the fifties parts stores sold short cast iron pipe with a flange on it that could be used to split a manifold. If you have some old 50s car magazines you may see them in the ads. I think it was Almquist that had them.
