Am I Lowered Or Not?

Just picked up an '88 LX Notch last week, and am going through things on it. Previous owner doesn't know much about it because it's the same way they bought it (they didn't change anything on it).

It was originally a 4cyl Car, but it now has a 351C in it.

There are no obvious things to show that is it lowered (different colored springs). Just by looking at it, I am thinking it is though.

Here's some measurements.

Front - Ground to middle of fender arch, measuring right up the center of the wheel: 25.25"...Tires are 165R15 with 40PSI
Rear - Ground to middle of fender arch, measuring right up the center of the wheel: 27.25"...Tires are 28x10.5-15 with 12PSI.

The rear is actually raised a tiny bit because the car has air shocks in the rear with about 30PSI in them.

So what do you all think? Is the car lowered or just sitting on sagged OE Springs?

So what do you think would be a good set? Just some OE V8 Springs?

Don't really wanna lower it, roads around here are crap and it bottoms out very often in the front and the rear tires scrub on the inside top of the wheel well.

Sounds good.

Gonna take off the air shocks in the rear too. Read some not so good things about them. Gonna do KYB Adjustable's all around.
