today a coworker of mine purchased a 2000 or so chevy 2500 with a 6.0 litre.. also installed was a vortec supercharger. the truck was all stock except for the s/c. first i will say that thing is pretty fast for an old man truck. from a dead stop the TITAN walked all over the chebby, from a roll on start the 6.0 litre was more of a race. from about 40 mph we mashed it and the TITAN was just a lil faster... anyways it was fun...
