Yes, it has a 455 with 6x heads mild cam, edlebrock 750, performer manifold and ram air restoration exhaust. The muffler shop forced me to put cats in 4 years ago. I will be removing them this year since I don't have to pass emissions anymore.
The story is that I didn't know it was an S/E till after I stuffed the 455 in it. the cowl tag doesn't have y84, but when i replaced the carpet, I found the build sheet and i'ts rigth there in black and white special edition.
