I have searched for hours and only found one person with a 6.0L and times it was rcsb 03 silverado ran 13.4 with 6L, what times have other people ran?

 

slowprocess will chime in, he ran a 12.5 at 106 or something.

 

You know me, always butting in. Yeah, I've gone a best of 12.54@105.40 with a 1.77 60ft. There is more left in the truck, but I am getting pretty consistant 12.6? slips. I feel that there is a low 12 left in it like it sits.

 

did you go to track with no mods or did u have all those and switch em when you did swap

 

I ran a 13.8 tonight on the heavy no traction 20's and with no 6.0 tuning. I could have done better since this was only my 3rd run but I got kicked out for no helmet For comparison the 5.3 would run a 14.3 on the lighter 16 inch rims and a 14.7 on the 20's. The 6.0 swap will be worth well over a second when I run it with the 16 inch rims and get it tuned.
