For sale is a pair of big block headers. There is no manufacture stamp on them so I have no idea who makes them. I tried to look them up on Summit Racing but could not discover a precise match but similar ones looks like they fit great deals of automobiles like, Camaro's, Chevelle's, Impala's, Nova's, and others. I have actually sandblasted and repainted them in the 2000 degree header paint. I attempted to put them in my 1968 GMC 4x4 truck however they were to long and hit the front driveline. I am in Etna Wyoming simply south of Alpine and I am asking $150.
