HP estimate new 468 comb

I know there are a few calculators out there, was wondering if someone would mind plugging in my numbers for a HP estimate

468
10.0 to 1
820 ovals, 2.19, 1.88, pocket ported with a bit of runner cleanup
lunati hyd roller, 241/249 @ 50
2 inch headers
air gap
850 demon


80 firebird with a 3000 convertor and 3.42 gears, partially stripped with a 6 pt roll bar. No et yet but a bit of street time. Wow does this thing pull.

It has a cast crank and I have the rev limiter set at 6000. What is max rpm with this crank.

Thanks

My 1980 Camaro ran 11.9s with a similar engine with solid flat tappet cam(Z-55). I figured mine was a little under 500 hp
