Well, as some of you know I have a shared 94 mustang 5.0 convertible. Today I replaced the spark plugs, wires, cap/rotor, fuel and air filters and ran some seafoam through it. Runs a lot better, still have the seafoam in the gas tank so that will work it's way through. I say that I LOVE the 5.0L... very easy to work on! Not to mention it's just a better motor!! Got some stuff to run by you guys. First off, on this motor, do the stock exhaust manifolds look like headers? Because the pipes coming off the cylinder heads look like headers, each cylinder has an independent pipe and they meet at the H pipe. I think they may be shorties? Either that or the stockers are very header-like. I'll get pictures if you would like. Also, I am thinking about the first mods. I am just biting the bullet here and goin with flowmaster, good price, trusted name and I have never heard flowmasters sound bad. So I was thinking order up like an american thunder kit, get an off road H pipe, and also while I'm under there install an air pump delete kit. Those several things all at once I think would be good? I also jacked up the back end of the car (when doing fuel filter) and the diff says "2 88" so I have a horrible ratio here, and according to that no limited-slip... but I turned one wheel, and the other turned the same direction so maybe it does have it? When I burn out, I get two nice black marks! Any input you give will be appreciated, I totally want to get into this car!
