    LS1, Patriot stage 2 heads, 226/226 112 cam, 4.10 gears and a converter. hoping to hit 11's with the new 231/239 111 cam and have solid 11's with a ported fast 92mm..then im curious to see what it will do with the nitrous.

    old mod list: H/C/I/N/E/G 408
    new mod list: 5.3, gears/posi, mufler and tune : (

    Just have the heads decked a little. Shave them down to get back to the compression level where you want...

    Go with at least a 3000 stall.
