Thats what this 390 had, shorty style cast iron manifolds with a straight 2.25 inch pipe going all the way up through the fire wall to bolt up to it. I thought it was really strange, did they race with that setup or would that system later be swapped out for long tubes? Like a set of Doug Thorley’s or something?
