hello,
i have seen a zenith-stromburg--cat-on-exhaust
manifold setup used for the twin su conversion..the
owner(me), lived in colorado(a smog testing state) so
i needed the cat in place for the test..I cut the z-s
carb manifold off of the cat-exhaust manifold..what
was left was a cat-exhaust manifold(for smog test
station..and a perfectly good place to mount my twin
su setup..i did have to space the su manifold a
little, as the flanges on the cat-manifold and su
manifold were different thicknesses ..
yours, Howard.
