Hi there- Another non-chevelle question, but should be similar...

On my Oldsmobile 455 (TH400 BOP) When i floor it while the car is moving- the engine bogs down- if i let off a little bit- the power comes way up- it doesn't seem to kick down. Sometimes if i really hold it to the floor, the engine will bog, then very slowly catchup.

This does not happen off the line- I can floor it and it will roast the tires and go like a bat out of hell, so i know its not the carb or the engine.

How exactly does the kickdown on a TH400 work? I know there is the swtich activated by the accelerator petal, but there is also a vacume hose connected to the back of the carb (quadrajet) that runs to the tranny.

Any ideas what is causing this? I thought i'd ask here before i start disconnecting things playing with it.

Thanks!
Ben
