I also say do what you want.....
It is my opinion, that through the hard work and research of those in ceg's past and present, we are now just starting to find out exactly what is capable with these cars. Since you are doing a setup never tried before(that i'm aware of) i say throw it on an engine dyno first, solely for the ease of parts swap ,and diagnosis while the motor is out of the car, and save your power and final tune pulls for when the engine is in the car...the last thing you need is to put this engine in the car un tested and discover a fatal flaw.
look a the Mumm brothers, i'm sure there near 300hp n\a 2.5 had more than enough enigine dyno time on befroe it was i nthe car for the fist time
