Anything I can do without voiding the warranty??
It is a sales pitch they phrase it as up to or something like that.

It depends on the Engine I have the 427SR/TW and it dyno'd on the engine stand at 507 hp and 520tq. They sent me the traditional 550hp ID plate. When I inquired why it differed from the dyno sheet I was told the plates are all the same cookie cutter ones. They don't differ, I asked for one with the right numbers and they accomodated me.

A rule of thumb is a manual tranny is 15% drive train loss so if yo have 450RWHP if you had 530 x .85= 450.5

Doubt you can do anything and not jeapordize the warranty, I know some have put different carb on (larger) for more HP or a different intake.

Another way is to inject it.
