My 1998 Regal GS doing a 20 to 95 run. We just got done putting the new(er) engine and transmission in tonight. Check out that milage ;-)
Performance mods are:
100k mile L36 longblock w/ L67 heads (9.4:1 CR)
3.29 gears in 100k mile 4T65E-HD
Pacesetter headers
3.4" pulley
180º thermostat
DHP 1.5 (tuned for L67 cam.. needs lots of work)
Intake
@krazz24 simple nose drive pulley....smaller pulley=much more boost.

The 3.29 gears help, Hes already in the powerband of first gear when he broke the wheels free, I can do it from a 30 brake boosted roll with the 2.93's. Mods are very similar but I have a real tune.
