"According to Lingenfelter, the production versions of the LS engine still leave a lot of room for performance improvement, they’re nowhere near the limits of the performance envelope. From what he’s learned about the new LT1, Lingenfelter fears that the motor, which has the highest specific output of any GM engine ever, 450 HP and 450 lb-ft of torque from 6.2 liters of displacement, may be closer to the limits of its performance envelope in production form than the LS. No doubt the LT1′s architecture can handle the 600 or 700 HP that the eventual ZR1 edition of the C7 will have, but 700 HP is commonplace in the LS tuning world and Lingenfelter is concerned that they may not be able to wring much more than that out of the new Corvette engine.
