hey guys im in the middle of building a 355 to go into my firebird and i feel like my desktop dyno is being very generous in the hp and tq ratings and i wanted to see what you guys thought. According to the dyno my motor will be making

564hp @ 7k
483tq @ 5500

now as far as whats going into the motor:
Dart Iron Eagle Platinum Heads 200cc runners 64cc chamber (got the flow numbers from dart)
Lunati 60113 cam (suggested by lunati)
Flattop piston -5cc
Dart single Plane high flow intake
holly 750 carb

what do you guys think?

 

Lunati says 6400 RPMs, not 7000.

DD is usually a little generous.

 

yes that was the other thing i found odd it sayd peak power at 7k when like you said its power band is good to 6400

 

my other question is whats the highest compression ratio id be able to squeeze out of this motor before going to race fuel? is 11:1 to high?
