Stock ET

With a 5 speed and street tires what ET and mph will a stock LS1 run? What about with slicks/drag radials?

A stock LS1 with a 5 speed probably won't very fast at all seeing as it doesn't exist.

The LS1's have 6-speeds, Mustangs have 5-speeds. I have heard of LS1's running 12.9's stock but they were freaks. I think most run mid to high 13's.

My best time is below along with my mods (pretty close to stock).
That was at about 63 degrees with the track at 1300 ft elevation.
My best mph that day was a 13.62 @ 106.5.

well my buddy has a 2000 firebird with the A4 all he has is a cutout and he runs 13.2, 13.3 on cold days.
