At last...a 5 liter...I love 5.0's

Depends on quite a few things. What else you got done to the motor. Manual or automatic. did you change the rear end gears if so what ratio. is it an LX or a GT? and how much money you wanna spend. I could go on and on.....

Assuming theres virtually nothing done to the engine: a favorite amoung us mustang guys for the almost stock engine, is the cobra intake. it flows some 500cfm better than stock, as way bigger intake ports and is not ported and polished but all the usually rough casting from the inside is smoothed out. set up looks like this http://www.google.com/imgres?imgurl..._GnCg&esq=1&page=1&ndsp=19&ved=1t:429,r:0,s:0

whoa thats a long ass link.

Teamed up with 40lbs injectors and a nice 70mm throttle body, and a nice COLD AIR K&N intake set up (just cause you got a K&N filter, doesnt mean you have a great intake system) should put out an additional 60 or so horsepower. You can typicall find these little gems on craigslist, junk yards things like that. They are not that hard to find.

On top of that the cobra intake has enough meat to port them even more than they already are. Be careful with this cause it takes more than just a port job to make it work properly.

If you do run that kind of set up, there is prolly some ECM mods you gotta do to maximize your hot rods potential.

a factory motor (no matter who makes it) is designed to handle a certain amount of air, fuel and spark. By modifying any of these 3 things, the other 2 have to be able to work with the new delivery in order to work properly. For example. You change your intake, well now you have more fuel and more air being forced into your motor. Now you have to do something with it! Horsepower is measured by how much air and fuel you can suck in, fire off and escape out of your motor. With all this extra fuel in air coming in, you gotta be able to fire it off (bigger and better ignition system, distributor, coil, cires things like that) and get it out of your motor (headers, pipes, mufflers, cats) as fast as possible.

Hot Rod Dave's 3 steps to cheap power:

#1 a nice intake system, Manifold, filtration system, fuel delivery.
#2 a nice flowing exhaust system. Flowmaster mufflers, headers (fox body mustands come with headers from the factory so your already partially there) and nice flowing pipes (enlarge them from its stock 2inch to a 2.5 or 2.750 pipes) and high flow cats.
#3 rear end gear ratio. a stock GT mustang comes with a 2:73 gear ratio. For mild engines a 3:08 is a nice gear but 3:73.....holy shit get ready to be thrown back in your seat!!

Being that Ive had 7 mustangs throughout my life. Those 3 things on your 87 (Ive had an 87, 85, 66. 65, 72, 93, & a 68) those 3 things are a great option for cheap power. All this stuff (if you do the labor yourself) prolly cost bout $3000, a good chuck of change but WELL worth the money.

I could go on and on bout 5.0's, cams, cranks, and heads will be for lesson #2....lol but right now ima play some cod and go to fuckin bed!!
