Dunno if it's in the 12's but if put a tire on it and hooked it'd be pretty close......I usually beat stock LS1 fbody's by about 1.5-2 truck lengths on the street. Drive it every day of the week all year round. Averages 15-16mpg too.

Nice! So there is hope with a manual trans!
Honestly I just want a fast truck & to me 12 sec is fast! I'm sure 13's would be fine too. My DD right now is a scion xb auto. If its not the slowest car on the road I'm betting its damn close.
