Well I did make my goal of 850 hp tonight on the dyno.:party018: But I am wanting to sled pull. people are telling me that the nv4500 wont take it. I have another 2003 truck in my driveway that has a 6spd in it. Will that swap help me out. Oh and i will be pulling in direct drive. 4th in the 4500 and 5th in the 5600
