Help!! im confused!!!!

The 392 will be a very de tuned motor, running 8.5:1 compression. the 700 hp is a very realistic number on a very mild street tune and not spinning over 6500 rps. The turbos can easily net over 1000 hp if tuned for a more race application. I could probably safey bring in 800 hp by leaning it out and revving to 7500 but the egt's will go thru the roof and probably take the paint off my hood. Every thing is a compromise, just keep in mind this is a street car and not a race car. The main reason for increasing the cid was to be able to get to the gt40 turbo range and stay out of the surge zone on the compressor map other wise i think id run a pair of to4e's .60 a/r and stay with the 5.7. Going to a single gt45 could also be an option but it lacks the "wow" factor and would spool a little slower.
