Switching from the TV rod to the Lokar linkage really added some tension to my gas pedal. It takes more effort than it used to, especially towards full throttle. Did everyone else have that problem and have to just live with it or is there some way around it? Beyond a certain point in the pedal travel the tv lever is maxxed out and the throttle is just pulling the slack out of the line housing. Seems like it should be easier.

Sounds like someone didn't get the geometry quite right.

The throttle and TV should max out (and hit idle) at about the same time. Of course, the original setup would also have been somewhat calibrated, so that the "expected" torque output from the stock engine across the range of throttle openings was matched by the proper trans line pressure. Swapping engines, trannies or carbs throws all that out the window.

Well I secured the line with the tv lever at about a 1/4 inch advanced like I read one guy did with his AOD setup. From there I adjusted it back and forth til it seemed to shift about right. Originally I had it adjusted so the tv lever and throttle were at rest together and the transmission started trying to tear itself apart at idle. Now it doesn't do that atleast...I do remember from observing the old rod that it held the lever open a certain degree at idle....which is what I've been trying to replicate...anyway I've got to head to pick'npull to help a friend so later.

You are correct about the original setup... You may be able to add to the tranny rod to reduce overall travel, so WOT and full travel are acheived at the same point... Also will reduce pedal effort...

What if I moved the stud farther up the throttle lever? It's currently at the bottom.

You got it... That basically reduces the ratio, so the same cable movement gives less travel in the lever...
