Horsepower estimate

Hi All,

I have a 355 sb w/flat top pistons running 10:1 compression, 327 double humps w/2.02 int. 1.60 ext., a 260/260 @ .050 .555/.555 solid lift comp cam, a tr1x tunnel ram intake and a Holley 750 double pumper. With this combo what is your estimate of horsepower to the flywheel?
