Bobber, I believe the offy is a better street mannered manifold, the cliffords big wide runners are for high rpms and really suck up the bottom end I was told,, the only reason I didn't use the offy was the flanges were significantly different thickness than the split irons I used for exuast, I could never fab up something that looked right,,though I wish I still had it now,, (Larry, do you still have it???)
