14.87@92.8mph in the mostly stock 4.8L
Tonight at Sac Raceway they had a special truck lane so instead of racing the Prius (the Z71 is being worked on), I took the RCSB 4.8L out to try for a new best since I had a feeling the air would be good.
The truck:
RCSB 2wd 4.8L 114k miles
Mods:
Magnaflow muffler on stock piping
K&N air filter on stock piping
M/T ET Streets 28x11.5x16
Shift point and rev limiter tuning
Time:
60: 2.26
1/8th ET: 9.56
1/8th MPH: 75.16
1/4 ET: 14.78
1/4 MPH: 92.8
Ran a few 14.8s and a 14.9 at the end of the night after the DA started coming back up. Overall I am pretty happy with its performance for being a torqueless 4.8L and pretty stock. I have a little weight reduction but nothing crazy. Just removed the tailgate, has a rollpan, light weight wheels and no spare.

Thx Tib 
Its set to shift at 6200rpm. Im hitting 3rd kinda close to the traps but not enough to try and run it out in 2nd gear. I just forgot how bad 3rd gear is in the 60E. It feels like you just lifted off the throttle lol. My 80E's 3rd gear feels so much better.
