Hooker Exhaust Manifolds 8525HKR
Just bought a pair of Hooker 8525HKR exhaust manifolds for my 69 C10. Unfortunately, they will not clear the motor mount frame bracket on the drivers side. Not sure about the other side, but it doesn't matter.
Distance from the centerline of the manifold bolts to the hump on the motor mount bracket is approx 3-3/4" . But you can see here where the Hooker manifold drops down 4-1/2". Not only that, but I'd have to fabricate at least one power steering hose. Lucky I bought them from Summit, because their store is less than an hour away. I would hate to pay for return freight!

You have to use the big block frame mounts.

Re: Hooker Exhaust Manifolds 8525HKR
Have you done that? Looks to me that even without bracket interference, the manifold would touch the frame.
