Actually, I had a set of these manifolds on a 1967 F250 camper/towing truck years ago. I used a 428 Cobra Jet short block with 1958 332 "factory machined" combustion chamber heads. The Police Manifolds were a bolt-in on the right side but my truck had power steering and I had to notch the manifold to clear on the left side. I ran a 2 1/2" system back to the rear bumper. It pulled a lot of weight and ran for thousands of miles. But then again we had REAL gas back in the day.
