I have been offered a SU HS4 carb and am wondering if it is worth replacing the Stromberg carb on my 13/60 herald with it. Has anyone any thoughts on this?

Why? SU is no better and no worse than Stromberg 150. The Dolomite1300/Toledo inlet manifold is actually slightly more efficient than the Herald
Stromberg one (even if the "rounded" Stromberg one "looks" more streamlined) and takes the HS4 carb, but is hardly worth the effort to get the right
needle and air valve spring. A decent tune up of the ignition system will bring bigger benefits than any carb/manifold change.
Only reason for changing would be if your Stromberg is completely sha**ed and the SU is perfect. Still need to get the right needle and spring
though.
The Stromberg can still be properly rebuilt so my advice would be to keep it original.
