My 68 has the quad still on it but I'm thinking about swapping to a edelbrock or holley. With a couple searches I found people singing the praises of the quadrajet over everything else, and then praises of edelbrock over any quadracrap in existence. I've researched the quad stuff to try and figure it out but its got so many variables to cause problems. I need the thing to run reliably and right now its stalling out when at a light. I can't be stalling out in heavy traffic around this crowded city of maniacs. I was able to get it running solid one day with a somewhat high idle but the next day I drove it, wanted to stall at every stop. Goes down the road just fine otherwise. The higher the idle the worse the dieseling on shutoff.
I'm considering using an adapter and putting a new carb to eliminate all the variables in the old setup. I don't know how old the carb is, if its the original, how many rebuilds, ethanol damage, modifications etc. I'm a bit worried about the rotary kick down switch and how to hook them up with the mechanical linkage since they are usually used with cable. I'm also curious if there is any other common way to actuate kick down since I don't see a source for replacement switches.
