A lot of guys threw the h.p. 440 exh. manifolds away too. Heck , I gave away a " complete" 426 hemi roadrunner exhaust back in the day. The guy turned out to be a mopar hoarder, and wouldn`t even sell me a hemi head out of a broken set, back when I needed one. He had a bunch of sets too at the time. Have no use for him now, piece of mopar sh-- as far as I`m concerned !
