I love bench racing!

My TBSS weighs well over 4600lbs and only lays down a 2.1x 60'....but will run a 8.9x's 1/8 @ 80.x mph and the 1/4 in 13.8x @ 99.7x... in the Texas heat. Thats a lot better then "upper 14's".

On a side note...my '01 C3 (5200lbs?) with the 325hp 6.0, duals with an x-pipe and a nice tune would run a 2.2x 60' and a 9.7x @ 73.69 1/8th with a 15.0x @ 92.3x 1/4. Tried and tried and never could get that heavy ass AWD truck to bust a 14.99.

all that said....my '68 GMC will be quicker then the TBSS before long!
