    modification 'path' for handling?

    Yes, there is nothing wrong with one of the spring/sway bar/shock packages if they are within your budget and progressive springs are a great compromise. My response was geared toward the fact that the original poster wanted to improve handling without giving up very much ride quality. It also...

    modification 'path' for handling?

    In a suspension PACKAGE, it is concievable that a front bar only being stiffened could be correct. The reason for this is that stiffening a sway bar has the same cornering effect as does stiffening the springs. SOOoooo.... if the package has MUCH stiffer rear springs, that might be the reason...

    Changing tranny oil questions

    Look around the auto supplies and you can find a plastic hand pump that will work in a one gallon oil jug. Use an old empty jug and pour in a few quarts. Always remove the fill plug FIRST! This will prevent you from draining the oil out and then finding that you can't get the fill plug out...

    modification 'path' for handling?

    Since you are interested in keeping a soft ride but want better handling, I would highly recommend that you add a stiffer rear sway bar. Do NOT stiffen the front sway bar, ONLY the rear sway bar. Stiffening the rear sway bar takes out some of the understeer. If you stiffen the front sway...

    Differential lube... what weight?

    Then 75W140 would give better gear protection for your climate. Good luck.

    Blew out plug

    I would first try carefully threading a new plug in place and see if it will torque to 13 ft-lbs. If you do have to resort to one of the heli coil kits, PULL THE HEAD to do it. Don't let the chips in the engine. To prevent this from happening in the future, when changing plugs ALWAYS...

    What diff fluid to use?

    Don't change the fluid, just add the friction modifier as BlackGT suggested. You can, of course, get it at the dealer, but most auto parts stores also carry it. Read the instructions for the correct quantity. You only want to put in as much as your car requires.

    Do you wash your engine?

    Dyno results Underdrive pulleys

    The slower alternator speed will only present a problem if you spend A LOT of time with the engine idling such as LOTS of stop and go traffic. The alternator output is regulated and the energy is stored in a battery. As long as the alternator gets some time at speed, there will be no...

    Rear axle tag

    A good explanation of the codes was given in this thread. I would like to add, however, that on later 8.8 units, there is no metal tag. They managed to save ten cents by putting a paper sticker on the rear cover. For thosw or you with a later car with the sticker, you might want to write down...

    Differential lube... what weight?

    This is one of those questions where it would be REALLY helpful if you had your location in your signature. You don't have to post your address and social security number, but at least your state. That way I would know your climate. If you live in a cold climate, use 75W90, in a hot...

    rear end howl

    Of course the pinion must be properly torqued with a new crush sleeve, but it is very unlikely that this would be the installation problem. When using FRPP gears, in almost all cases you can simply install them with the same shims that were in the original setup and it will be okay. What...

    Dyno results Underdrive pulleys

    I have had underdrive pullies on my 88 Vette for over 100,000 miles with no negative effect. They will be going on my GT in the near future. There is absolutely NO tuning necessary when changing to underdrive pullies.

    What harm could gear whine do?

    Tires will sometimes develop a roar over time. This usually happens when they are not kept rotated. Have you kept them rotated? Just because tires do not roar when new, does not mean that they will not get noisy as the miles go by. Good luck.

    how to install gears.

    A pinion depth gauge is very handy, but is not necessary and not a justifiable expense for a hobbyist who will do this work only a few times in their lifetime. To begin with, you should PLAN ON using FRPP gears because in most cases they go in perfectly by just using the shim sizes from your...

    Stalling problem?

    The fact that it happens only on damp days would normally indicate an ignition problem. In the days of distributors, ignition being the problem would be a virtual certainty. Assuming this is on your 2001 Mod motor, however, it's hard to imagine damp air causing ignition problems. I would...

    how to install gears.

    To do it properly, you will need a dial indicator at the least. It is best to have a press to press the ring gear and pinion bearing, but it can be done with a hammer and a brass drift for the ring gear and driving the pinion bearing onto the pinion with a proper sized length of pipe. NOTE...

    What harm could gear whine do?

    Before you do anything to/about the rear axle, are you SURE that the noise you are hearing is rear axle noise? These days it is getting more and more common to hear tires that roar so loud you can't stay in the car. Have you kept your tires rotated? Have someone drive it to verify that the...

    detailed rebuild right up

    Although the book is now aged, there is a book written by Sean Hyland. Although it is entitled something like "The 4.6 Ford Modular Engine" it covers the 5.4's as well. The copy I have is aged, so it does not cover the 3V engines, but there might now be a revised edition. I would google up...

    Building Engine, Need Opinions!!!!!!!!!!!!

    If you are planning on spinning this engine to high RPM, which I expect you will given these mods, you REALLY need to use forged rods. The pressed powdered iron rods will not last long with continuing high rpm operation. When a rod goes, so goes the rest of the short block and maybe even...
