I did the dual SU (HS4s) conversion for considerably less than the
above amount. I was able to buy a new set of HS4s for about the
same price as Apple Hydraulics charges to rebuild and rebush
an old pair. A used pre-1974 intake and exhaust manifold ran about
$50 each (you will need the pre-1974 exhaust manifold anyway for
the Weber conversion). Then, all you need is a head pipe to
match the manifold and a set of flat air filters which will
clear your brake booster.
My suspicion is that a good bit of the performance problem
assoicated with the Zenith-Stromberg carb is due to the
dreadfully inefficient saxiphone-shaped exhaust manifold which
they used on that model. My low rpm torque improved
dramatically after I made the conversion.
