the rams horn manifolds should fit the 67 and back cars from what i remember. they did a test on the large rams horn manifolds years ago and found they flowed as well as small tube headers.not too shabby .some of the late 60 s early 70 chevy trucks used rams horn mainfolds that turned back to clear the frames on the trucks. it may clear the frame on later elcos not sure though
