there is a 454ss pump that offers a quicker ratio than stock, not sure that would help but seems to be a nice "upgrade"
That's a steering box bro.. Nothing wrong with my box, just the pump. From what I've gathered, pretty much all of the pumps are essentially the same flow wise. Doesn't look like nothing to be upgraded to.
