    Highest rating was 325HP. Flywheel.
    Obviously...some have made that at the wheels stock.

    I could be wrong but I think an SLP optioned out LS1 Camaro and maybe a fireahawk were "stock" rated more than that.. Can't remember the exact number -- I think it was 10-15 more HP?

    But we all know the LS1 is basically a 350 hp (crank) engine.

    I forgot about the Firehawk. I guess they are technically a T/A.
    But yeah, overall they are all 350-360 at the crank.


    Who has the highest BONE STOCK dyno sheet here?? Might be a thread for the dyno section.
