2354hp !!! Motor by 3V Performance. Boostdoctor on the keyboard 427 dart with our Kryptonite hydraulic roller cam, Johnson 2116 lifters(NOT short travel) and factory LS7 rocker arms with CHE Precision Inc. trunion upgrade. We believe that is the most power ever produced from a LS with long travel lifters and stock rocker arms. And we have never had a valvetrain failure during the 2 years that we have ran this setup. | Boostdoctor/Drive-By Racing
