    gears and a stall would be your best friend move up to a 3:73 gear and a tight 3200
    Simple: 408 on steroids!

    i did 409 with the ls6 intake manifold and 226 cam.

    i swapped to the 231/239 and put down 229 hp...then i added the ported fast 90mm and havent been to a dyno. dont put too much thought into dyno numbers. its all about how it does ont he track.

    i would like to see your current dyno chart.

    that 229 is a typo ( right lol )

    working on putting the LSXr car intake on now, ran into a few bugs BUT i'll get it straighted out

    hoping to see closer to my quest for 500 to the wheels, 480-490 i might be happy lol.. but i doubt it

    i dont see anything else i can do with bolts ons!!

    guess plan B may happen sooner !!!

    yeah it was a typo lol. 429hp before the ported fast 90. im guessing my peak HP is around 445ish now. im stuck on the bolt ons too. i can re-do my Y pipe and pick up a little, and maybe an EWP but an aluminum 414 is looking really good right nwo.

    i dont think reaction time matters, its your et is based after you roll the beams.
