throttle cable issue

[1972BlueC20]

Is it possible to have a situation where the throttle cable is either adjusted wrong or bad and needs replacing?

My truck is running great, but it seems like it should be much stronger when I floor it. It just doesn't get up and go like a 350 should.

If it can be adjusted please let me know how!

Or if anyone has any other ideas as to why it wouldn't have the power it should.

The timing is correct, the truck has a brand new carb and all new ignition parts....it doesn't miss at all....runs really smooth


Thanks in advance!!
