I want to identify a manifold hot air riser tube, so that I can sell it. I suspect that it is from a 71-76 big block full size car with single exhaust. I recall a single exhaust BB engine that had the shroud opening further back towards the firewall. The tube is longer than a 69-72 442 dual exhaust tube. The attaching holes are slotted and closer together. Thanks, Bob Ryork442@aol.com unknown tube left, 69-72 442 tube right mounting holes mounting holes 11--1/2" long
