Unless they have made major improvements in the castings, the 455-HO reproduction intake is only suitable for idling off a trailer and on to a car show field . To make any HP with that manifold, major epoxy work or welding will be required to move all the runners around to make them fit the heads properly and straighten them out. Probably in the neighborhood of 10-12 hours of labor to make a decent intake out of it. Just a heads-up.
