Would some of you mind climbing under your dash and looking to see how much play, if any, you have between the gas pedal when it is pulled all the way up and the throttle cable? I've got at least 1/4 to 1/2" extra play in the cable. Made me wonder if I'm able to open the throttle on the carb wide open. To test, I took a small pair of vice grips and took up the slack - brought the pedal a lot higher. I made a quick run up and down the highway and it felt like there was more oomph with the vice grips on than off, but that could have been imaginary (I didn't have someone to actually check on the carb for me in the driveway). I have a Q-jet and an Edlebrock performer intake. If I'm not mistaken, I bought the Edlebrock bracket that lifts the cable mount on the intake a little higher to compensate for the increase in the manifold's height, but it was long enough ago that I'm not 100%. Some time when I have a second pair of hands I'll see if the pedal to the floor with the current amount of slack will allow me to go WOT.
