Horsepower guess?

I have settled on this setup and am wondering about how much Horsepower it will make....any guesses are welcome. Also...compression with this setup?

360 block bored .030 over
Stock pistons and crank
Magnum heads
Summit K6901 cam...with magnum rockers lift should be about .470
Edelbrock Air Gap magnum intake
Carter AFB 625cfm
Stock exhaust manifolds until I can get headers
Dual exhaust with glass packs

Thanks!
