SM 465 gear ratio

Was looking for the gear ratio in a 4speed in a 77 chevy. My brother built a 468 and is doing some truck pulling and we are trying to fine tune the gearing, but don't know what the ratio for the transmission gears are. Thanks in advance for any help on this. Gord
He is running in 2nd gear in low range 4wd @6500rpm with 4.56 axle ratio and 30 inch tires, needs more wheel speed, but we are not sure what ratio to go to, 4.10 or 3.73 or what. Broke the front ring gear last time out so now is the time to change it, if we are going to. All input welcome!
