So, I'm trying to get my new 700r4 dialed in...and I'm finding that I'm not getting WOT from the pedal. (my buddy puts pedal to medal and I'm only open 2/3 of the way) Maybe I'm being over-critical but it seems like the geometry of the original throttle leaves a lot to be desired when WOT is critical. (And my gas pedal seems to be a loosey-goosey set up too)

Since I'm updating the trans, should I consider updating the throttle linkage to something a little more effective?? (and hopefully not a nightmare to install)

Ideas would be appreciated.....just something simple but effective for the new 700r4

I'm attaching a picture of the TV Cable bracket I'm using (TCI) and it includes a spot for an OEM style throttle cable.....but I'm not sure what aftermarket throttle cable would fit. Obviously it would be a tidy set up to utilize this bracket for both TV and throttle cables...

If you're using the stock pedal and linkage, all you should have to do is adjust it to give you a higher pedal off the floor. That should get you to WOT with it mashed to the floor. Another alternative is the Lokar pedal assembly.

Thanks, I will probably adjust the stock linkage for now, and work towards installing that Lokar throttle. I see Eckler's sells the throttle pedal, and also a cable that looks like it's been sized for our cars.

Chevynut, Do I adjust the pedal with the one bolt on firewall where pedal and throttle arm connect?...just loosen/adjust/re-tighten?


Thanks for the responses

Don, definitely the rod is adjustable (stock rod) but I thought there might be another way to adjust the pedal height alone. Looking at the connection between pedal and throttle arm, I don't think there is any way to adjust...so I'll do what I can with carb rod adjustments.

I'm pretty sure the Lokar throttle cable will fit into the top portion of the TCI bracket. Then I can keep the bracket and Universal TV cable I'm using.

As you shorten the linkage to the carb, the pedal should raise off the floor. It's a pretty simple linkage. ;)

Got 'er done this afternoon. TCI bracket for QJet with mounts for my Universal TV Cable, and Lokar Throttle. I also installed the Lokar gas pedal. It will take a little "getting used to" as it sits a lot higher than the stock gas pedal. But operation is nice & smooth. Thought I'd share pics of the completed job.

ha ha, I am running into this issue as well. The tci adaptor for the carb also is in the way of the manifold vacum port. My trans is a 200r with a tci adaptor and change to vacumn.

My build is on a budget so I am thinking of grabbing a GM car gas pedal and cable. anyone else do this? if so what car did you use it from?
