single or dual carb setup

[KerryPinkerton <pinkertonk@xxxxxxxxx>]

I was LUCKY a few weeks back and ran into a deal where
I ended up with a COMPLETE set of these cross rams,
long casting, spacers, exhaust manifolds, and risers. 
Included was another partial set AND a 60 Chrysler
(non Imp) that runs.  Really fell into it and got a
great deal.  One set is going on my 57 Imperial
Roadster.  The other will end up on Robert Soule's 65
300 after we fabricate the missing pieces.
