    So, as stated in my other post, I'm back to tinkering with the GP as a DD. I'm stuck between doing a stocker build and SC build.

    But, "while were here" gets me every time and i stack mods on mods and do nothing. Either way, If you could build any S/C 3800, what would you use, using as much stock parts as possible.
    So, what block, which rods, which pistons, which heads/SC/Intake and lastly what cam?

    Headers are going on the car, but ive heard and read so much about the SIII vs SII, Gen V, XP cam, yadda yadda.
    I'm considering SII stocker with an XP cam, bigger springs and pushrods and letter fly. I'm not looking to race, but I want a reliable, S/C, DD that gets better mpgs that my GTO here on Fort Bragg...

    annnnnd GO.

    since it hasn't been noted can you use e85 or not? E85 would change the build and change what the mileage is going to be. also which is more important the mileage or the hp outcome?

    Add intercooler and that's what I've been running for 2-3 years.

    Better mileage would be my thought on this one, since he's got the goat for the horsepower needs.

    Definitely looking for a little more mileage.

    I usually fill up before I head home on the weekends, drive 200 miles, and get like 20.9 as an avg.

    Then, the rest of the week my commute to work involves stop and go traffic. My avg is then dropped to 16-18. I'm mainly gonna burn up the highway with the GP. And it'll also give me another vehicle thats still fun, but not outrageous. Also, I can have the GTO down for a few days while i'm installing parts.

    ^ yea that recipe will never do yah wrong.
    Jenny, The '99 Silvermist GTP. With the mod's that matter.
    I would rather lose by a mile because I built my own car, than lose by an inch, because someone else built it for me. Your car is your story, so don't let someone else write the book.

    Gas prices are never going to be any less. I don't think I would do a larger cam. I'd throw that money at an intercooler. I wouldn't do anything that would compromise mileage. The higher compression will help on both ends.
