Last season I saw a Loaded Hemi reg cab 2wd running 15.2 consistently
Were at 500 feet above sl. No spare, or rear bumper.

Lightnings range up here from mid 14 to mid 13's, it all depends on the driver and the 02-03 vs the 99-01
A slightly modded 02 L was running 13.25-35 all summer and eventually won the points race for street stock.
Et streets, cat back, fan, off the shelf chip and intake. Can't get more consistent than that.

As far as the SRT-10 I doubt I'll ever see one up here and if I do it won't be at the track.
