those are 318 A-body manifolds. if i remember correctly, that is. they should measure around 1 7/8" or so pipe diameter at the flange that bolts to the manifold. maybe someone can correct me if i am wrong.

You are correct, I misread the casting number.

You are correct, I misread the casting number. Ya was kind of hard to read. I had to use my 250 readers with a magnifying glass.

If the center exhaust port has a divider, they are 340/360 manifolds, if no divider they are 318 manifolds The 273 and 318 ports are smaller a slightly different port shape also
