Twin powervalves, siamesed throttle bores and many other surprises inside!

Pretty cool stuff Max. I always thought they might come out with a new 81, but I guess they feel it would not be a good return on investment?

I spoke to the guys at stromberg about the 97 on the larger engine in my 33,
They said this was coming out,sure would be nice,
We sure are lucky to have guys like this making stuff to keep our old fords going as goodc as new.

Any guesses how this larger 97 would perform on a stock or slightly modified flathead? Is 250 CFM too much? This seems like a simpler solution to a multi-carb steup.

Cool! Questions popping all over my brain...
What is the bore diameter for that flow?
Pump squirters are re-angled, presumably based on study. With them pointing thataway, are they still the conduits for the power enrichment or has that been redirected into main circuit?
Is the extra adjustment screw for off idle transition?
The siamesing below throttles would make them seem somewhat bigger to the engine than fully separated bores, yes?
