Hi Jack,
One thing I will say about the Stromberg to SU switch
is that it is not as inexpensive (initially) as you
may think. Still cheap in terms of HP-per-$ gained,
but not inexpensive. Here are my running costs so far:
-Two rebuildable SU carbs bought off eBay: $40
-Intake manifold bought off eBay: $60
-Rebuild kit bought from Burlen UK: $90
-Two new K&N air filters: $70
-2 New needles: $25
-2 New jet bearings: $30
-Miscellaneous (new intake manifold gasket, hardware,
PCV valve, etc): ~$40
So, all in all, about $350. Still not bad, but more
than I had initially thought -- and even more if you
end up paying more for your carbs and manifold.
