GP engines nicknames?

Is there a nickname for GP engines or no? Besides GP15-'s.

I have not heard of any

Rolling porchs

Brick on a skateboard. [:D]

Geeps

Good power

Going Places.

I know Geep was a common term for GP-7’s and GP-9’s, but it is commonly used for newer power?

GP - General Purpose. We have a couple of old Santa Fe GP 60’s, but almost everything GP here is used for yard work. I have never seen anything higher than a GP60 in our yard.

If you mean as in calling SD9s Cadillac’s, for the long, long hood and smooth ride, then no, I have never hear of the GP class being referred to as anything other than Geeps…
