    The first mod I think you should do is to get a free flowing performance exhaust system. A free flowing exhaust is the best way to get the maximum out of any future modifications you may want to do. Add will give you the most bang for the buck.

    What is a typical price to have someone change the gear ratio? Cost of parts and labor = _________ ( Just a rough estimate) I am thinking of getting a Ravin performance muffler from Midas but also have a Flowmaster that I am looking at. Any suggestions on mufflers?

    Thanks, Jason

    Well for EACH axle you will probably be looking at a guestimate of $500 to regear. You have the cost of the R&amp;P= $150 (roughly, depending on brand), Install kit= $100 for a good one that includes all bearings, labor would typically be anywhere from $125 - 400 an axle. Just depends on the deals you can find around your area. As far as the muffler goes Flowmaster is good as well is MagnaFlow. I use MagnaFlow, it flows a little better then Flowmasters because it is straight throw, it also has a deep rumble to it, but I'm considering a FlowMaster just for the louder sound. I'm unfamiliar with the Ravin so I can't offer any advice on that.

    well just an estimate but 4 wheel parts said they would do my front for just under $300 so i would say around $600 to do both front and rear give or take a few $ as far as mufflers i am running duel flowmaster's as well as alot of other people around this site

    The better the engine breathes, the more power it make. Free flowing exhaust, and intake. The two best things I ever did to my truck were true dual exhaust and MSD ingition. The MSD will help out alot too.

    My Chevy isn't broken, its just out of gas.

    I second what these guys have said.

    There is no cheap, significant improvement in performance aside from NOS.

    The Ravin mufflers are LOUD, but not nasty sounding like a glass pack.

    After the good exhaust system, the best bang for the buck would be a new intake manifold and cam, but that might require a new chip.

    Other than that, for big power increases, there really isn't anything easier and better performing than forced induction! You can get a Holley supercharger for less than $1500.

    As for gears, DO IT! this will make more of a difference than exhaust or a cam. It may be cheaper to just swap the axles, than to pay for new gears and setups. Maybe you can even get a little bit back from the junkyard for trading in your matched set (maybe...)

    well wat i see is the trendy and easy horsepower adder these days is all those stickers, they add at least i'd say 5 hp per sticker, so go and buy as many random stickers as u can, it doesnt matter if u've never heard of the company or if they specialize in Fiats, the more stickers the more horsepower. Also, if u add racing stripes and a spoiler the size of rosy odonnell you'll get an easy 25 hp.

    I have an '87 and I added 3 inexpensive things that gave me a mild, but noticible amount of HP: an open air intake K&amp;N air filter, a TBI spacer and dual exhaust. The combination of these things made a noticable difference. All together it cost me around $350.

    Think of your engine as an air pump. The more air you can move through it, the more power it will make. Adding an intake and headers will make a minimal improvement, since the restriction of the head ports and the valves is still in the way. Adding a hotter cam will make a nice improvement, while ading a cam and better flowing heads can make a shocking improvement in power. Forced induction is totally amazing, provided that the engine is capable of dealing with the additional power without self destructing.

    Would true dual exhaust without headers still make a noticable difference? Headers can be a hassle, but I'm not totally against them.

    Just have to find good deals on things. I got lucky today and got a set of ported and polished heads with 2.02 and 1.60 stainless steel valve, a performer TBI intake, 454 throttle body, and a banks ram air intake for $500. The heads havent been on a vehicle since being done, intake and throttle body are a month old, and the ram air is 3 months old. I bought them for a friend who owns another shop, he had them to put on his 87 k20 but put a 502 in it instead.
