What times should a 04 reg cab 5.3 3.73 2wd. Run in the quarter mile? then add like nelson tune and headers. temp bout 70 degrees outside.
Thanks,

My guess is 15.30's

 

My stock 03 reg cab 5.3 3.42 2wd ran a 15.7 stock. With a westers 93 tune and long tube headers stock exaust 15.3.

 

well some arent as lucky, my stock 5.3 ecsb ran 16.4 with exhaust and air intake and headers, at about 80degrees , so dont get excited, until you go to the track

 

oh yeah then i added a tune, and 4.10's and no Im running 15.7

 

man i thought our trucks were faster than that. my ex's dads ecsb ran 16.2 and it was what he pulled his camaro to the track with. if i dont do a lot better than that im gonna be upset.

 

my 2000 rcsb 5.3 3.73 2wd ran 10.0's at 71mph in the 1/8 th and 15.50 in the 1/4.
my 2004 rcsb 5.3 3.73 2wd has ran a best of 9.90 at 72 mph in the 1/8th, no 1/4 passes yet, but I would guess that it could get mid-high 15.30's from those numbers. Probably consistent 15.40's.

Also noticed 04black silverado posted 15.2? in the 1/4 stock a few posts down, but I believe it stated 46 degree weather.
Track, elevation, and weather can make a difference though.

 

My 04 RCSB 5.3, 3.73's with 500 miles on it bone stock ran 14.97@89 mph in good weather. With headers and a tune you should pick up .5-.6 tenths.

 

WOW!!! 14.97 stock is impressive. I guess I'm going to have to get mine to a 1/4 track and see what it will do.
