Adjust gas pedal (Solved)

[Gears And Circuits]

I have a few ideas but I need a little advice. Currently the stock pedal hits the trans tunnel and prevents the carb from opening all the way. I can only get the engine to reach 3k rpm. Would it be better to cut the bottom off the pedal or move the pedal away from the firewall?

For reference I have a 1980 Supreme Brougham swapped to a 350 chevy. I'm using the Summit street/strip 600 cfm (Holley) four barrel single pump. the cable and pedal are original.

It would be better to find out why the pedal is hitting the tunnel and then correct the problem. It's not as problem with the factory pedal or it's position if in the stock location

Let me clarify, i'm bad at explaining: Pedal to the floor does not open the carb far enough because it hits the carpet. The amount of deflection isn't enough to pull the cable all the way in. I believe the position is fine, this car only has 100k on it. Do I need to modify the pedal or the cable?

is that a new carpet and is it laid down properly?

No its original. This car had the v6 in it, which leads me to believe Olds never intended anyone to race that model. If i block the mount on the firewall it should allow more travel without moving the starting point of the cable too much if at all.

The pedal itself might be loose.Mine came loose one time,so I replaced the factory screws that held it too the firewall with some loctited nuts and bolts.

the Monte SS, Hurst Olds, Olds 442, GP 2+2 and Grand National and every other G body all had the same gas pedal assembly mounted in the same place and they all used the identical carpets

Perhaps you need to bend the rod on the pedal side of the pivot to allow more travel before the pedal bottoms out. Otherwise, the bracket for the carb is not correct, and needs relocated farther back to give you the correct amount of travel. The universal ones that bolt to the drivers rear carburetor bolt have worked well for me.

If your car was originally a 2 barrel your throttle cable could be too long/short. I've never heard of a pedal being screwed up that bad.

Well if l read this all right your running a Holley and not the quad. So l would think your problem is at the carb.

Put up a pic of the carb set-up on the car, that would give a better idea of the issue.

In 30 plus years l am yet to come across a fuel petal issue.

I know for the 600 Holley l put on my elcamino l had to make up a bracket to hold the cable at the carb.
