J-2 Rochester Tri-Power

Looking for information regarding the operation of the vacuum-actuated outboard carbs on the 50's J2 engines with tri-power. Text and photos will be very helpful.

74-79 Ramcharger or 100, slant or no motor - not interested in v8 - Overdrive 4 is a big plus, NO hopeless rust buckets!!!
3Rd gen F body floor pans/camaro door skin (L)

Why is it I see so many "Proud to be an American" bumper stickers on the backs of cars made in Japan or Korea??????

I would suggest a factory shop manual for a 57 Olds to start with, I just did the 3 carbs on a 59 Eldo I am rebuilding,

Re: J-2 Rochester Tri-Power

cool. I'm trying to duplicate the setup on a small block Chevrolet. I've been told a progressive mechanical linkage would be easier, but I'm still stuck on the concept of vacuum signaled outboard carbs. It seems to me that it's more logical to use engine load vs throttle position to bring the secondaries online, more streetable that way.

I never knew they had Eldos in '59 - obviously they weren't front drive then? I'm certain GM's FWD started with the 66 Olds Toronado. Funny how front drive was only for classy cars back then and now it's the other way around.
