well boost it and instead of NOS get a meth-H2O injection kit. You won't even need a cooler. I'd probably supecharge it. Easier and you don't have to hack up your engine compartment. If you're talking about a basic 440 for the street. Get a set of good light rods/pistons, roller cam, E-heads (or similar), headers, RPM intake, Holley 950DP, and a stall and gear to match your cam. Then hit it with a 200 shot. Depending on you car and the set-up your could be in the 9-10 second range.
