>>So you are saying that an improperly installed throttle cable bracket, or a throttle cable attached to the wrong place on the throttle shaft, or too short of a throttle rod, (67-68) or too much insulation on the firewall, or a damaged kickdown cable won't prevent the secondarys from opening completely? <<

You forgot to mention if his feet were too short and couldn't reach the peddles.

My info about the linkage had to do with him not understanding why the throttle wasn't opening as he thought it should. If he understood that it didn't have vacuum secondary's and understood that they should be opening. Perhaps then he would have investigated if the insulation was too thick or his legs too short.

His choice to switch to a Holley shouldn't be based on what he didn't know about the Edelbrock any more than it shouldn't be based on what YOU don't know about the Edelbrock.
