All good info, thanks for the tips. I have a 68 350 that came with a 2 barrel. I'm wondering if there was a difference between two and four barrel cables and/or pedal assy. The previous owner put in a different 350 with a quadrajet and when I bought it, he said it never did make a whole bunch of power. Found with the pedal to the floor, it just fell short of starting to open the secondaries. Might be something to check.
