Yes, I'm familiar with the 1LE's. I've had a slew of F-Body's! The one I miss the most was my 1990 L-98 Formula 350. I had a 355 in it with ported heads, ported intake, ZZ9 520 lift cam, headers, off road pipe, CAI, Drag Lites, 2500 stall and a whole bunch of other stuff!
My last car was a '99 SS with a Z06 cam, headers, off road pipe, SLP dual/dual 3" cat back, lid, 160 thermostat, LS1 edit, Yank converter... It was a mild set up A4 that put down almost 340 RWHP and ran low 12's and looked and sounded almost stock!
I loved the Z-28's like yours. I also had 2 of them, but they were not 1LE's of course.
