I have a quetion.

I've decided to get a 408 longblock from D&D and put an ATI D1SC with a 3 core intercooler at either 10/12 psi. This going to be a street car with a little track time. Do you guys think this will be enough sc for this setup or do you think I will need to step up to the F1. Here's the setup.

408

INCLUDES A SEASONED 351W BLOCK,
4340 FORGED STEEL CRANK,
4340 FORGED STEEL H-BEAM RODS,
FORGED PISTONS,
AKERLY & CHILDS MOLY RINGS,
CLEVITED BEARINGS,
D & D MAIN SUPPORT W/STUDS
H.V. OIL PUMP,
BALANCER, FLYWHEEL,
BILLET TIMING SET,
CUSTOM CAM,(between .650 and .700)
ARP FASTENERS,
FEL-PRO GASKET SET,
205 AFR ALUMINUM HEADS with some porting,
CRANE HYDRO. ROLLER LIFTERS,
MANLEY PUSH RODS,
SCORPION ROLLER ROCKERS,
BALANCED, BLUEPRINTED

How fast do you want to go?

It's going to be a mostly street car, but I would like to get around 600-700 rwhp out of it. :)

Anyone?

I'd go with a bigger blower just cause its a 408. Thats alot of displacment to fill. I think the D1 is a 1400 or 1600 cfm unit, look for altleast 1800-2000 cfm for good Efficiency.
