You said a 383, so I'm going to assume it wasn't a LS1 motor but a LT1 or TPI type car? I think is important because your LS1 is not designed to have the low end grunt a LT1 or TPI car would, its designed for high RPM power, so the torque of the TPI/LT1 really stands out in the midrange. building a stroker LS1 will gain the torque and HP, but it is still going to be higher in the RPM range.

Think about compairing a stock LT1 against a stock LS1 and all else being equal, the LT1 or TPI car will out pull the LS1 down low, but once you get above 5,000RPMs the LS1 motor has all the advantages.

That said, regardless of LT1 or LS1, a stoker will have more torque down low then a forced induction motor, because of both the stroke as well as the higher compression, but the turbo will have the most high RPM gains, so you should look at what you want from the car and build it for that.
