HI , I am looking for some help on the hot air tube and manifold shroud usage for a 1972 455 with the dual exhaust manifolds. I know the steel shroud part is being reproduced but I am having trouble finding the tube that connects between that and the air cleaner snout. I have a couple of tubes for the 350. Will the 350 tube work? I do not have the 455 put together as of yet so it makes it hard to try this out ,physically going by dimensions of the two engines the 350 tube should not work, but if I am mistaken on that please speak up. Anyone know where I could pick up a tube that will work?
