Unless you are slipping, a overhaul probably won't get you there. What rear gear are you running and what trap rpm are you turning?

4.30, RPM's unknown as it's time out was 1/8 only that day. I won't run out of RPM's in the 1/4. I know a fresh transmission with a MV would offer something, just not sure if it would be enough.
