460 is at the machine shop. i expect it will dyno at 400 hp and 500 ft lbs torque or close anyway. i am going to run a c6 trans and 3.25 gears. i know traction is going to be an issue. tires are 255 60 r15. what can i do to help this truck hook up a little. i got some time before i get it installed and just want to do my homework. thanks for any input i really apreciate the wealth of knowledge on this site and enjoy learning abut these engines!
