help on dual quad manifold request

[willyp]

Wow!, thought I had learned some but the FE's are really confusing, thanks much for all the info provided so far, I checked Carl's parts as listed above & found they have complete sets, manifold, carbs, log & linkage, they list the Blue Thunder medium rise w/BJ-BK 600 carbs & a Cobra C5ae-e Ford manifold w/BJ-BK carbs, would these be a better match for my heads than the low rise manifold I have?, also the BJ-BK carbs I assume are the new "Ford" carbs as described above, are these progressive? & would the linkage set that comes w/these match up with the throttle arm from the ERA? I'm asking here as I've called Carl's a number of times & never received an answer or a call back! I want to go to the Dual setup & can off set some of the cost by selling the single system that's on the car after the swap & if the Blue Thunder or Cobra manifold is a better match for my car I can sell the earlier dual manifold I have now, making the swap & having the same performance as the single carb would be acceptable but if the mismatch of the low-rise versus the medium-rise would cost some I'd rather go the other way. Again thanks for all the info so far, I've been watching all the answers/info provided & trying to do some "checking" on my own & I still have a LOT to learn LOL!!
