Thread: 500 CI LS race block?

  1. #1

    500 CI LS race block?

    I saw this motor advertised in a car craft mag and haven't seen anyone talk about building one. The ad says it can be 500 CI any one have an opinion?

    a few have built it. SAM did one with a LS2 added a plate to top of motor to gain stroke, personally id stay away from it. a 427 can make plenty of power if built right. Sam also has a 434 that dyno'd highest NA recorded

    2002 Silverado - 427Lsx w/ Twin gt4202s
    2010 Silverado crewcab Z71 - 5.3litre w/ procharger
    2000 Wrangler - 5.3litre with some stance
    2014 Xsport- 3.5 Eco boost

    it ain't that I'm too big to listen to the rumors, It's just that I'm too damn big to pay attention to 'em..That's the difference

    I saw a display from the company who does the plates while on the 2009 Power Tour. I thought it was a fairly ingenious way of adding cubes to the motor myself. I don't have a clue as to whether they will stand up to abuse or the larger stroke or whatever ... I just think they took a kewl approach to an old problem of not enough cubes.
