400+ HP x 2300 lbs x 11 sec Feasability

The charts and calculators are handy, but you need to realize what they dont take into account. Namely, the rest of the powertrain, the tires, the noise, the street driving. At 355 to the tires, you will need to stick very well. Not radials, but soft race tires, with a really good suspension. Much more than a set of Dunlops and a pinion snubber. You'll need a set of gears that puts the engine in the right spot in the power band in the traps..that may be 4.10s or higher..May not be the best cruiser gears..and if you drive it mostly, the gearing can help or hurt the experience. You'll need a convertor that also puts the launch rpm where it will be most effective, and maximizes torq multiplication. That could be 2800 10", or 4500 8" that feels sluggish when just driving at part throttle. If it were me, I would use the longest arm (stroke), so the milder gearing and a lower stall design can be used. A mild 408, with the right convertor and suspension, will go faster than 11.90s in that chassis and be drivae/cruisable too.
