on my 02 5.3 i already have cold air, throttle body spacer and some of the free mods along with a reg. flowmaster 40 with no cats.. truck has 150k and i run 15.6 with peg leg rear end and 3.42 gears.
about what kind of times should i run with the new stuff im puttin on it.?

LPP long tubes and ory with hooker muffler and electronic cut outs for the track, thunder tune pcm, posi with 4.10 gears and underdrive pulley.

 

15.0

Extended cab or Single cab?

 

extended

 

Should run better than that. Mine run mid 14s all day long with those same mods. Went to a 3200vig and run 13.9s. But your truck has a few miles on it...

 

4x4 or 2wd?

 

I say at least a 14.5.

 

Yeah mine and my buddies ext cabs were identical other than he had shorties and i had long tubes and they both were neck and neck around the mid 14 to 14.2 and that was the best pass..

Oh and lglowes truck is a 2wd. I think someone asked..

 

yeah thanx shawn. i would figure somewhere around the 14.5 range atleast

 

oh you are 2wd, Im going to second the 14.5 range

 

really that quick? my dad just ran his 01 5.3 ext cab, 2wd last night, with cai, longtubes, ory, and 3.42s he got 15.4s and 3s out of it, i was only getting 14.55s all night, should have been a bracket race
