FAST ADJUSTABLE LSXR (MEDIUM RUNNERS)
Run with the medium-length runners, the peak power output jumped to 593 hp, but note that torque production dropped through most of the curve. Such is the trade-off inherent in changes in runner length. The shorter runners must be teamed with a cam profile that will allow the motor to rev to the effective operating speed of the runner length. Equipped with the FAST adjustable LSXR intake (medium runners), the 6.2L produced 593 hp and 512 lb-ft of torque.
