How to tell what engine you have.

I got my 96 Mustang a year back, and i was told it has a 98 V8 in it. I want to verify that because originally it had a V6 in it. I want to know 100% that it is what it is. not a 2000 4.6 or something like that. How can i do that?

The '96 though '98 GT modular 2V engines had the wasted spark EDIS ignition system, using two coil packs and plug wires:



The '99 through '04 use the coil-on-plug (COP) ignition:



It will be "in-your-face" obvious the moment you open the hood...

That would be the only way to nail down the year of manufacture, however it really doesn't matter for buying parts stock or aftermarket as from '96 through '98 they were all the same...

8th digit of the vin if its a x its a gt from factory, and 10th digit dictates what year it is.

I believe that is not the issue, he already knows the car was a V6 from the factory, and now wants to know specifically what year the NPI 2V that's in there was made.

I am not sure I understand what it is you wish to know? We have established that is it a NPI engine (having dual coils and plug wires), and that all '96 to '98 NPI engines were for any repair/build purpose identical.

Why is the specific year of manufacture so important?

X2 the block doesn't have to be the same year as long as it's a 4.6 2v

I just want to know forsure what my engine is. I'm not pulling it just for the sole purpose of knowing. I have alot of maintenance work that im doing as well, I just would rather know if the guy told me the truth or not. He's lied about some stuff already so i cant take his word for it.

Okay so first off, the ignition system does not necessarily decide the year of the engine. If he swapped a PI engine, he could have kept the coil packs/wires.

That being said, it is more than likely a Non-PI engine. Especially if it still has the coil packs.

I did a 98 to 2001 engine swap. Here's a comparison between the two engines. Note that I converted to COPS when I did my swap.


You can look at the alternator, which is differnet between the two.

The oil fil cap on the valve covers is different.

One piece on information that could help, the 98 is the only SN95 with a return fuel line. This means there are two fuel lines connected to the fuel rails on top of the engines. This may or may not help you, as if it is a 98 engine, it is rather unlikely that the person doing th swap bothered to keep the return fuel line. It would have been quicker to just swap over the fuel rails from the 96 engine.

If your engine looks indentical to the top photo in my picture, then you probably have a 98. But it could be a 97 or 96...it's hard to tell

Read the OP's original post, "He" took out a V6 and installed a V8, there were no coil packs to be preserved...

I was just saying that the person who did the swap could have preserved the coil pack system, as in not convert to COPS, or they could have converted to COPS. Not that they preserved the coil packs from the V6. I was posting pictures of both of my engines so he could try to see what his current engine is.

Regardless, it is pretty easy to tell if it is a V6 vs V8, and if it is a NPI or PI motor. Which as you guys already said, if it is a NPi motor the year is insignificant. All NPI motors have the exact same set up (same flywheel, valve covers, etc) so it would be hard to tell the difference anyways.

Well then it Is a 98! That helped me alot! I do have a return fuel line on the rail as well and it looks exactly like the picture. Now i know forsure what im dealing with! Thanks again! Also, im replacing the headgaskets in a couple of days, should i just get pi heads, intake? Or save up for something like trickflow?

Well if you're doing the headgaskets, you might as well do PI heads. You can save up for the trickflow heads but personally, i dont think it is worth it. For the price you would put in the heads you could almost supercharge your car.

If you just did PI heads/cams/intake you would see a gain of ~40-50 horsepower, which is quite a jump.

Glad I could help!
