I know my 68 340 had power steering and manifolds. I honestly can’t imagine any a body small block manifold hitting the power steering box. Truck manifolds?
The ones that came with the 360 "turn down" and go back. The stock 318 ones "turned up" and go back. And from pictures I have seen the 340 ones turn up also. So I,m sure that is why they turn up to miss P.S. box. So I would think they would work.
