Default What are your thoughts - s480 455

Here is a complete setup of my engine currently.
455, .030 TRW forged pistons, stock rods with ARP bolts, Factory N Crank, Factory caps and bolts. Compression comes in at 9.57:1.
Edelbrock heads - flow 307 cfm, 2.11/1.77's, round ports, 89cc.
Butler Performance metal head gaskets with copper coating. ARP Bolts.
xr288hr-10 Comp Hydraulic Roller - Specs are 236/242@.050 with 600/620 lift with the Harland Sharp 1.65 Rockers, 110 LSA. Spring pressure is 160 lbs on the seat.
Multiple intake manifolds to use - all port matched. Torker II, RPM, and Northwind - Would lean towards NW for this setup.
FiTech EFI - 1200 HP capability. Has 8x80 lb injectors. Fuel pressure set at 58 psi. Using a Tanks Inc fuel tank, Walbro 400 lph fuel pump, and -8AN feed lines, -6 Return. Aeromotive Fuel Pressure Reg.

Th400 Trans, 10 inch UCC torque converter - stalls at 3400 rpm and is relatively tight.
New driveshaft being built currently with 1350 joints.
10 bolt rear, Strange Chromoly yoke, 3.42 gears, Moser axles, braced cover, arp carrier studs, 1/2 inch wheel studs.

I'm wanting to turbo this thing. The car runs 7.15@95 mph currently in the 1/8th mile. Full steel body, full interior, etc. Roughly 3800 lbs.

If I were to get the headers built - already got them priced out, get an s480 Turbo, and figure out a way to intercool it, would it be able to live with 8-10 lbs of boost until I can get another shortblock built to handle more abuse?
It is a mostly street car but I love to take it to the track.
Any input is appreciated - and yes I know....Stock Rods
