Hey, thanks for taking the time to read this. I ran across a car for $100 last week that didnt run. I was able to get it running for under $11.00 (starter Seleionid). Currently im in the process of chaning the plugs, wires, o2 sensor, distributor cap, roater, air breather, pcv valve, and the exhaust so i can get it to pass the state inspection here in missouri.

Im 24 years old and know general maintance of cars etc, but as a child i always helped my dad work on his 57 chevy. I want to get a nice hot rod project car like that in the future, but im using this car to learn on.

From my experiance i dont see a differnce in HP using more expensive spark plugs etc.

Since i need to replace the exhaust on the car, i may go ahead and get some headers, and then replace the exhaust. and i would like to put dual exhaust on it if possible.

The car does have a catalic converter, so would i need to get 2 to have dual exhaust? or does it Y after the converter?

what other modifications can i make to the car that would increase the HP?

from what i know about the car / engine its a V8 302, (would rather to have a 351c but im not going to go through the expense of replacing the engine, and since my dad is not here i am uncomfortable taking a job on like that this early.

so the main questions of this topic are basically....
1. Whats envolved with putting on headers and changing the exhaust to dual exhaust?

2. What other modifications increase HP, that dont require pulling the motor completly out of the car?

3. Do you notice a differnce with the more expensive spark plugs (i.e. the platnium 4)

The 85 LTD is built on the same platform (Fox) as the 79-93 Mustangs, 83-88 T-birds, Fairmonts, & Mercury variations of those cars. I got a whole dual-cat Mustang exhaust system from headers to mufflers for my T-bird free from a guy who was hotrodding his Mustang. Stock or aftermarket H-pipes will work, though your column shift may need modification. The stock iron manifolds will not work with Mustang pipes, so you must use Mustang headers. Mustang rear ends also bolt in, & you might find one with posi & gears somewhere. 5.0 Mustang brakes (87-up models are bigger), wheels, quick steering racks, & sway bars can also be used. Your car has a longer wheelbase, so the Mustang driveshaft will not work.
