I have never seen these before. A ,300 cubic inches, air cleaner decal. I think that there is 6 left..

 

I am pretty sure the NPD and Dennis-Carpenter catalogs have the 300 decal. Have not ran across any, yet, for the 240.

 

I've love one of those.
I kinda want to get a custom one that says, "300 H.O."

 

After some research I figured out why I've never seen one. I get the 80-86 years catalog. It's in the years prior. Plus the one on LMC appears to have a checkerboard patern on the ends like the 302 ho decals have but its too blurry to verify that. Pretty sweet if it does. I'd prefer that one.

By the way, that is gross horsepower, not net.
