Guess on 1/4 mile time?
 

Ill be runnin my truck friday night jus to see what it will do...
07 classic rcsb
4.8
Ls6 cam
S366(9psi)
Stock trans& converter
3:42 rear
30" tire

No idea of power output this willbe the trucks first pass on the track
Any estimates
Thanks

13.0.

Depends on the tune and if you build boost at the line and can hook. It has potential to run high 11 or very low 12 in cool weather but hot weather and with the stock converter probably mid- low 13's. Gonna be fun!

to much tire, not enough gear for combo


id say 14s with that combo

15.5@90.

instead of guesstimating just go to the track?

Im takin it to the track fri jus wanted to see what yall thought

my first thought was too much tire

High 12s

Mine ran 14.00 at 101 with stock trans and 3.42s on 275/55/20s on 4.5lbs. I think you can run a high 12 with a 109-110 trap speed. Added a loose converter to mine and bumped it up to 9, and it went 12.09 at 110 with a 1.69 60ft on drag radials.

07 Classic 4wd rear mount ran 8.9 1/8 (~13.8-13.9) on 5.5 lbs with 4.10's & 32's and I was able to leave at 2300. Same as your 30" tire with 3.90's. 8.5 lbs in hot weather 8.11. Cold weather with no changes 7.64. I think you'll be impressed if it will spool quickly. Good luck Blackrat!
