How can you tell if a 5.0 was previously a four-banger?

I just want to check to see if my car started out its life as a 5.0. I don't have money for Carfax, so are there any tell-tale signs that show? How does an 8.8 inch rear end look like? I know the suspension is also different with the four-bangers, too.

Well, if they didn't swap out the front springs, the front of the car would sit a couple inches lower. Smaller front disc brakes, smaller master cylinder, no quad shocks...

http://www.mustanggt.org/main.htm That site has a vin decoder click the little drop down menu in the middle of the page. Then go to 82-93 Mustang Vin Codes. Scroll down to where it says Digits-8 Thats all the engine codes. Then all you need to know is the 8th digit of your vin.

If the 8th digit in your VIN is an "A", then your car was previously a 4-banger. If it's and "E" then it's an original v8.

When the 2.3L Mustang engine changed from single-plug to dual-plug configuration, the engine code changed from A to M. The 2.3L M code engine was in the Mustang from '91 through '93.

Not allways a bad thing if it has been converted. Possably a fresher motor and tranny. Maybe the car has an 8.8 with gears you never know. If it is a 7.5 rear it has either 3.73's stick or 4.10's if automatic.

Um, no. If it has a 7.5", it has either 3.45's stick or 3.73's auto.
