    Differences in 275 & 300 HP Nstar

    May be a dumb question, but what does GM do to get 25 more HP in the 300 HP Nstar? I imagine some of it is in the heads? Maybe different cams? Just curious.
    Thanks

    Sorry, did not intend to be redundant. Will do a search, as directed.

    From my driving experience behind the wheels of both Northstars, the 275hp version has good low and excellent mid range power, with good top end power but the 300hp version has astonishing top end power, with good low and mid range power.
