That is probably accurate. They came on late 60s -70s vehicles.
The " ram horn" is supposed to be the best performance oriented stock manifold for SBC GEN 1 engines.
They are what came on the (probably 70s) SBC that was in this when I got it.
I knew they would fit back up, and bolt to the already existing exhaust.
So they worked out pretty good!
I just wish I would have had time to heat paint them before installing them. Oh well.
