The "self revving" at quarter throttle is just the nature of the beast of a non-IC pump. My 91 did it, Bill's 600hp 89 did it, my current truck does it now that it has a 114 pump. Get it to the rpm of peak torque, and it takes off. As long as the rpm comes right down you are ok.
Is your throttle bouncing at lighter throttle position in 3rd gear? I.E, when you mash it in 3rd, does it do it? Or is it more an issue when trying to maintain ~25mph in 3rd?
