I was looking to gather a bunch of info on the NA/5.3L club in one thread. If you would like, post your best ET/MPH along with supporting mods/weight reduction etc. that it took to get you there. If you know the DA during that pass, thats great. Post it.

I tried searching, but it's very hard to find this particular subject because NA and 5.3L is just used so often. Maybe if this type of thread has already been started, give me a link.

Crew Cab/Extended/Single cabs, all welcome....

Its not that fast compared to all the modded trucks but my 04 RCLB 5.3 a4/3.73 2WD went 14.64 @92 MPH when it was new and 100% stock.
If I take the splits from another run it shows that the truck could have gone a 14.52 on the perfect pass.
It did go a bunch of 14.7s and 8s.

 

all the mods are in my sig. i did not use the slicks with this run. 14.7@94
