408ci CR/and hp/tq # est.?

I am building a 408 with the following:

Callies compstar crank
Callies LSC I beam rods
Diamond flat top Piston -2cc valve relief
317 milled to 68cc w/3 angle valve job and slight port work
g5x2 cam
stock gm lq9 gasket
ls6 intake

I was wondering what HP/TQ #s do you guys think ill make through a m6 also what compression ration would I be at?

any input is appreciated!

Sounds like a good budget build, would be very interested in results, thinking similar build in a yr or 2.
