Had twin Webbers on an 8 port xflow head....only used one throat in
each though.

First OHV twin perhaps... wasn't the "Peashooter" OHV?

This is a lame "me too" for the not so financial, at the time. The Hillman
Californian ran a Zenith POS which used to warp its base admitting
air,..instead of scraping it on the cement path, I tried a grey motor
Stromberg. It had the same 2 bolt spacing, and the engine seemed to like it.
No rejetting of course (what was that?). It did tack on 8 mph to the 1390cc
top speed of 72 mph :-) and dropped a couple of MPG Had to use a red-motor
airfilter,..the oil-bath unit was a bit too tall.

Sorry, that's what I meant.

I believe so, but then if it's not a twin it doesn't seem like a HD to me.
