potential whp/torque no's?

[AmericanSoldier]

headed to the dyno in a few weeks once my performance shop gets its new EFI software up and running, what should i expect for whp/tq no's?
i would also like to know how much torque these cars put down stock?
thanks for any input and/or guesses

without the spray id say you might push 240 whp.

i say 239.5 whp and 325 ft #'s trq
with n20 305 at the wheels and 389 trq
