IGNITION

I did my search and i could not find the answer I was looking for. I am looking to upgrade my 95 5.0 and I was looking at a MSD distributors. My question is are they worth the cost on a stock engine? I would also install the coil, new plugs and new wires. Any input would be great. Thanks.

MSD=Might Suddenly Die/My Spark Disappeared

No, they are not. MSD is not very good quality anymore, they've got the name and that's pretty much it... Go with Crane ignition systems if you want something good... but you don't need to, the factory setup is more than enough. If you have no issues with your ignition system right now, leave it alone and spend the money elsewhere.

Lots of people do make the mistake of doing the ignition on these cars btw, tons of advertising talking about power gains/hotter spark etc... etc... None of that will make a damn bit of difference with a stockish/bolt on car. Even with a HCI I ran the stock ignition on my Cobra and it was fine.

And of course do new plug wires if you need to, but just Motorcraft ones are fine. Or FRPP if you can't find Motorcraft. Don't fall for the "omg make your spark a meeelion volts" wires either... that's snake oil too.

Thank you. I am glad you told me that before I spent the money. I know this is off the subject but I did research and couldn't find the answer to this, I would like to change the ring and pinion. My question is how do you know if it has been changed without removing diff cover? As the tag says, I should have 2.73 ratio but I think it has been changed. 95 5.0 T-5 I run about 2500 at 75.

IGNITION

Jack the car up and see how many revolutions the drive shaft does when you spin the wheel one full revolution .

My 91 turns a little over 2000rpm at 75mph with a 15" rim and 3.55 gears.I've got 17" on it now.You've most likely got a 3.73 or 4.10 gears with that rpm/speed & 17" rims.Do like 5pointoh mentioned. Make a mark on your rear tire sidewall & one on the driveshaft too.Jack the rear of the car off the ground,let a buddy slowly turn the wheel one complete revolution while you watch the mark on the driveshaft. If the driveshaft makes 3 3/4 revolutions while turning the wheel one complete revolution, you've got a 3.73.....If it makes a little over 4 revolutions,you've got a 4.10....If its a 3.55 gear,the driveshaft will make 3 1/2 revolutions.
