Do you know what these are?

I'll give you a hint. They are from a small block Chevy

Split manifolds to run dual header pipes off each side

LOL kind of. Do you know what they came off of? It was one of the coolest Chevy of the late 50's. Pretty fast for back in the day..

Not sure but I think they ran a balance tube from one side to the other on them didn't they

These came on the 57 Black Widow.
The “Black Widows” assembled by S.E.D.C.O. (Southern Engineering and Development Company), used a special made exhaust manifold made by Fenton.

The cars and garage below belongs to a guy up in Ohio. I have been all through this garage and checked out most of the stuff in this picture. He also had number 1 off the assembly line, #1 1954 55 and 56 Corvette sitting in there the time I was there. Can you just think of the value of cars he had in there at one time. Boggles the mind. The Widow is suppose to be the real deal. It was sure slick. He said it was a wreck before the restoration.

Anyone have anything they want to try to stump someone on? Rare part or ?
