    Sounds interesting. I assume you’re adding a programmer as well? Are you doing these mods for the track?

    Strictly a cruiser, just looking for excellent street performance and highway cruising. I'll have it dyno-tuned
    post build and decide on programmer, I don't think I'll need to go that route

    Okay! Finally got to the results part. I'm going to try posting some pictures. It's my first time and I'm old, so bear with me, please.
    The work is complete up to the car being at the dyno. which when they were hanging the Borla exhaust they discovered that the old exhaust was last done in high school shop class by some teenage stoner. He had cut off all the stock hangers and welded on his own. Anyway I'm hoping to get the car back this week.

    WOW!! That's pretty impressive, I didn't mean to make the photos so big. I'll have to work on that.

    Avatar looks like an "Igor Sikorsky" 53?
    I worked on HH3E's at Clark AFB.

    Nice looking Car.
    I always loved those rims.

    Those Headers should "SOUND" nice open,
    but probably won't "FEEL" anything extra until you are well over 5k RPM.

    Keep us updated

    ...and will likely kill whatever bottom end power you have.

    not what i'm going for, these are advertised as mid range. i believe midrange for my 5.7 will be around 3-3.5 G when i choose the Comp 270, all the mods for this upgrade, my target has been to be at or near top end in this range. If not, i may have some low milage 5.7 parts for sale. i'll let you know
