    you came in speaking garbage of modding kills MPG, which is true and false depending on how you address the question.
    I'm not stating false info. Your facts are no more fact than mine as these mods did make my milaege decrease. I'm stating my experiences, as are you. Ohh wait, you haven't been into your motor yet have you?

    Just putting in my experiences here. For the most part everything I have done to the Camaro has resulted in almost no mpg changes. The exceptions of course are when things like my cam was new and I had a heavy left foot.

    The steps I have taken so far in mods have been

    1.Long tubes, true duals, and a tune (helped mpg some, I think the old tune was bad). 356 RWHP

    2. Cam (226/228 .584/.588 lsa 112) along with all the other goodies that come along with it (springs, oil pump, tune, etc). 397 RWHP

    3. Moser 9" with 4.11s. With this one my city mpg has stayed almost the same. I just used a higher gear and skip gears alot (would say it is better, but city driving is hard to gauge accurately). At highway speeds I did not loose much if any because I now drive around 75 instead of 80.

    Driving style has played one of the largest factors for mpg in my experience. The Camaro has and will be my daily for a long time and usually sees about 1000 miles a month (often more), with most of my travel time being on the highway.

    it also depends on how much of the work you do yourself.
    I pulled my heads and bought the bits ($65) to port and polish them myself. I found the cam I wanted 220/224 .570/.580 112lsa (a regrind) on ebay for $123 shipped. 3,000rpm stall $140 shipped (also ebay). pacesetter LTs $450 shipped. 2 ten foot pieces of 3" pipe for $70 and fabbed up true duals. plus a bunch of other small stuff

    when I bought the car it was stock and got 16mpg. now with all my mods I'm getting 20mpg

    I'd say longtubes, used fast intake/TB and dyno tune by the best shop in your area.
    Maybe get a decent muffler if you want to keep it quieter.

    Maybe a 3.73 too?

    Even a used FAST intake is not considered best bang for your buck. Unless cammed and headed, hold off on the FAST unless you have spare money laying around.

    I sure didn't mean to start a war.

    If you simply look at the LS1 as it progressed in later models, the power went up and the mileage stayed the same (98 vs 2002 Camaro). Look at the Vette in 98 vs the 2009 Base Vette with LS2. Bigger cubes, about 90 more HP (340-->430 GM ratings) and slightly better MPG (using new mpg numbers for both cars). So I KNOW more power does not HAVE to cost in MPG. I'm not saying that adding a cam that adds 100 HP almost by itself will not hurt mileage. It will. What I'm looking for is the right combination of parts that will give me 50-80 HP and keep mileage the same. The answer may be to use ported LS6 heads, LS6 cam (mild), coated headers, and stock mufflers for my old man quiet requirement. Maybe an underdrive pulley to boot.

    I've seen used fast intake / TB for $500, that was a while ago.
    If I planned on building a forced induction setup, I would pass on the FAST

    Some headers are more than $500, so the banging for bucks is close.

    To me gears is the best bang for the buck, LT's with ORY or High flow cats, SLP Lid, Exhuast cut out and muffler would follow. Ofcourse other then putting nitrous to me gears is a very good mod for the money because all the other mods your putting on the car the gears will help you use those mods more effectively by being in your cars power range longer and getting there sooner. Your gas mileage will suffer a bit but well worth it to me with the amount of benefits it will give.

    No damn way a USED FAST intake and TB goes for 500 bucks. Maybe just the top shell.

    You musta been high when you saw that price.

    stock internals. full exhaust, full intake, and a tune for street use will get you the best combo of mpg and power. after those mods it will only go downhill with mpg, uphill with power. im in an a4 and i get 24 mpg on a regular basis. half highway and half city driving(without play obviously). i havent done any road trips with this car so i dont know my highway mpg.
    2000 white z28, t-tops, free mods, intake, full exhaust, dyno tune, repro c5 z06 wheels, and some elbow grease here and there.
