Quarter mile estimate...

So since my last post I went a whole new direction due to picking up a buddies lt1 for $1200. He's swapping for 5.3 LS turbo. Enough back story.

The LT1 has

K&N CAI with aluminum elbow
TB bypass and air foil
LT headers (I think hookers)
Gonna do a ORY and probably a LM1 catback
CC503 cam with matched comp springs
1.6 rr
Ls7 lifters
AC delete
Cat delete
Tuned ECU
I have 3.73 gears
Built A4 with shift kit
3000 stall
And will be running DRs.
probably weighs 3200-3300#

The track I race is 3500ish elevation
Whatcha guys think?
is it good for 12s?

Stock heads? I have the exact same mods minus the 1.6rr and LT1 CAI [mines the SLP lid swap] and my car ran 12.44 at 1000ft... when the DA was around your elevation it ran low 13.1 "ish"

High 12’s/low 13’s in good weather with good traction. None of the 2.xx 60’ crap.

I ran an 11.77 at 3500' with 330whp with a 2925# raceweight....I would hope that a car with similar power to be able to run well into the 12s at 32-3300# in similar air. The car will make the power to do it.
