Stroker- want more ponies

I've been running a 408 for a few years and of course want more. I've been seriously considering a newer hemi but just can't seem to pull the trigger. Can I get another 40-50 hp out of my current build and still run pump gas

360 bored .040 over for 410 cubes
Fast efi
Rpm intake port matched to ported rpm eddies
1.5 roller rockers
Lunati voodoo 705 hydraulic flat tapped. Can get numbers if anyone requires
Forged Pistons 10:1
Cast crank
Stock windage tray
Car is a street brawler that sees the track a few times a year
So is there any room here ?
