I know this is extremely late but I just joined recently. I have a 92 Z28 with 323 gears automatic transmission cold air intake and cherry bomb muffler with an ACC 3800 stall lock up converter. Everything else is stock and I ran a 13.57 and 13.58 in back to back runs in Delmar Delaware

 

Wrong forum.... 3rd Gen 1992 engine (L98) is not the same as 4th Gen 1994 (LT1).

Threads like this are so pointless.

 

I thought I typed 94. I'm sorry. My car is a 94 Z28. I have 2 actually.

 

This. I ran 13.87@102 in a few month old completely stock 1997 Z28 M6. And a lot of 14.0's and 1's.

Actual timeslip for run

 

Delaware has good air and a low altitude plus the torque converter helped a lot but it's amazing how Camaros went from like 15-16 second 1/4 mile times to low 14 to high 13 second times. Chevy definitely wanted to shut down the mustangs of that era
