Re: Overdrive for a 454?
4l80s are all electronically controlled.
I have heard of "built" 700s that can be used in high horsepower/torque applications but have no knowledge to pass on about them.
Google is your friend. Do a search, apparently there are manual valve body conversions you can do. But you do lose the "automatic".
