    some BOSS 302 dynos

    Pretty smooth torque curve. First graph is narrow/tall so seems more volatile.

    I dont really know, but im sure they can hit that easily. The 13 GT's have 420hp so they can get another 24hp pretty easily. The BOSS has "CNC ported cylinder heads with 1mm bigger valves, different cam profiles, short runner intake manifold. Forged internals help keep her together to the 7,500 redline." Thats the difference between the 2

    Very impressive numbers.

    I am extremely confused about that exhaust setup. Can anyone educate me?

    Oh, haha, wow I must have totally overlooked that when I saw pics of the 302. I didn't realize that it had side exhausts. Cool!
