Christopher,
Can you describe the underslung anti-vibration rod to me pleeeaaassssssee
I have a pair of TWM intake manifolds for DCOEs. One of them has a cast boss
that goes downwards and has a hole facing the engine block. I have not been
able to figure out what it was there for. The linkage kit that came with the
manifolds did not heve any extra stuff that looks like it went to the lower
boss. Other than that the linkage looks as nice as any I have seen.

I suspect you have a side draft manifold, and they are talking down draft
manifolds. Though for the life of me I can figure out why someone would want to
pull SUs & put on downdrafts. You are addig at least a right angle to what was
essentually a straight shot to the valve pocket.

I have gone to too many vintage races I guess. I just love the look of a row of
DCOEs. AND I just HAD to have a car that had multiple DCOEs (Of course now if I
had a V-8/12 engine it would have been duel venturi downdrafts lined up between
the valve covers). So the TR is getting DCOEs because I think they are cuter
than SUs. But, realizing that all I would get is poorer petrol milage and maybe
lower power on the low end if I just poped DCOEs on, there is a header, matched
polished ports & valve pockets, oversize valves, more compression, a 280 degree
cam and the shrouding around the intake valve has been removed. So the DCOEs
shouldn't be a total waste.
About the Holly clone of the small duel venturi down draft Webber (DRV?),
I believe the design was licensed from Weber by Holly and used in the Ford
Pintos & Merc Bobcats on the inline Ford 4cy during the 70s
