BBC Throttle Arm

I need some help. My throttle arm is hitting the back up my head and not allowing the gas pedal to come up high enough to get full throttle. With all of the slack out of the arm a fully mashed pedal will only give me half throttle.

If I had a straight throttle arm it looks like it might work. Any suggestions? I would like to stay with the rod setup and avoid a cable.

Thanks,
dj

Re: BBC Throttle Arm

There are a few ways around this. I have had the same problem. Different things come into play here....if I am understanding the problem. The height of your manifold and if you are running a spacer can change the alignment of your throttle arm (are you talking about the metal piece from the lever attached to the firewall and what attaches to your carb?). You may have to find a new position to attach the throttle arm on the carb. What carb are you running??? Those arms can be bent to make things work. Give us some more details on your setup.

The motor is a World Products 540, which has a single plane high rise intake and aluminum heads, AED 870 4150 carb without a spacer. It is the arm that attaches to the firewall that is causing the problem. The car had a 350 in it which allowed the arm to piviot closer to the carb. The heads on the new motor appear to be sitting higher than the small block and preventing the arm from getting as close to the carb as it was before or it may be the Polyurethane motor mounts have the motor sitting higher.

I can still attach the rod to the carb, but it leaves the pedal to close to the floorboard. I will try and get some pics up that will help explain it better.

Re: BBC Throttle Arm

I have seen some threads that a 6 cylinder arm works. On my BBC with 3 7/8" valve covers I had to use a lokar gas pedal with a cable.
