Default 416 stroker rwhp guesstimates

Hello, just about to assemble my motir, what do you guys think it will make?

Lq9 base
4.065 bore
4" stroke
Ls6/243 heads - hand ported/5amgle valve job, bowl work etc
Victor jr single plane port matched
92mm TB
1 3/4 headers full 3" true dual exhaust with x pipe borla xr1
Mn12 t56 with McLeod twin disk
1piece DS
3:91 rear gears
Prostar wheels all the way around (shaved 62# of stock equipment)
42# injectors
Rings are Akerly and child's Plasma moly top ring and Napier seconds
Compression will be around 12:1

Deffinatley want over 500rwhp, and yes I know these heads are really going to be holding me back.

I will when the funding allows it, along with better heads. I just can't swing any more $ right now. Literally 100% broke haha, so I'm doing it like this to get it back on the road.
