Danny, I think you're on the right track, you probably need 6600 or more. Also, you might consider moving up to a 5.86 gear.

Of course, that depends on how good your engine is. It has to be good enough to turn the necessary RPM, and make power when it does.

Consider that 5.57 with a 2.52 low and a 6600 converter is considered a decent base line for a stout big block SS car.

Get your converter out, get the serial number, and call the manufacturer to see what it is supposed to be doing in your car, if it is supposed to be in there. That will give you a good starting point.
