Any ideas on what the combo below will put down? My goals are 450ish rwhp with great drivability (I know most of that part is in the tune but I have some good tuners local, Masport comes to mind).

OEM Blackwing lid
226cc Advanced Induction 243 Heads
BTR Stage II cam with supporting hardware
FAST 92mm
TSP 1 7/8 Longtubes with off-road Y
OEM SLP dual/dual catback
Stock rear for now but down the road most likely S60 3.73

Undecided on clutch but it will be a twin disk.

Thoughts on this combo?

Depends on the dyno, but around 450 sounds about right

Any other comparable porting options? I'm in SoFla and would be nice if something was reputable and local. Here are the places I know of:
