  • LS2 VS LS1/LS6 Engine

    Without getting way too technical, what are the biggest and most significant differences in the LS2 engine? I know it is 6.0 Liters with 400hp. That's about it.

      actually, I don't know of any differences either, other than it is a 6.0L engine this time. And isn't it like a 3-valve pushrod motor or somethin? I heard that somewhere......
      my car:
      '86 Caprice Classic. Soon to have a 350 crate motor. Shooting for 300rwhp.

      the project:
      check the www for pics, but a '36 Chevy Master Sedan, MII front end, Jaguar IRS, '93 LT1 powerplant with plans for 350rwhp, and many many other goodies

        Still 2 valves.

        Compared to the LS1, the LS2 has freer flowing intake and exhaust.

        The LS2 also has a 10.9:1 compression ratio, and a 6500 RPM redline.

        It has higher compression, and more displacement, with the same redline as the LS6. This is why I think that 400 HP claim is vastly underrated.
        Former Ride: 2002 Pontiac Trans Am WS6 - 345 rwhp, 360 rwtq... stock internally.

        Current Ride: 2006 Subaru Legacy GT Limited - spec.B #312 of 500
