122K s55 runs 12.5!!
Went to the track two weeks ago with a friends 2003 s55 and went 13.2 with a 1.99 60ft. Not to bad with the miles but I told him lets put plugs and K&N filters in it, also a new johnson pump. I did that and we went back out tonight to Cecil county dragway first run 12.58 at 111mph with a 1.88 60ft. I was shocked it went that fast,he told me to run again and it went a 12.6 with a 1.98 60ft. It was a fun night and I thought some of the s55 guys would want to hear how a high mile car does and its not to bad!

miles mean nothing on an engine...
If you take care of it ... it will run the same times as it did when new or better since an engine tends to loosen up over time...
I have had many Turbo Regals..Grand Nationals for the common folk
I have had ones with well over 150k miles and nothing done to the engine including orginal turbo .. they were running mid 11's @ 115-120 just with a few bolt ons.....that is a 3.8 v6 20 year old buick technology....lol
Now I have a GNX that I am going to soon mod...it has 80k miles on it....
