Briefly, the intake/exhaust bias on the camshaft will be different, and likely the LSA as well. The torque curve will be different, possibly requiring a change to the torque converter. And the change in the RPM bands may require a gear change. It requires considerable testing and development, you can't just give specifics off the top of your head. And then you have to realize that the dyno may not tell you what it wants at the track.
