13 second NNBS CC 5.3
 

Do you or someone you know have a 13 second NNBS CC 5.3? Wanting to know what mods.

N/A...not Forced Induction

Quit playin.. u already know what to do...

word
im 14.4 you got better gears an your camming that thing youll be deep in the 13s

Just trying to see how many people tried it. I know most people just drop a 6.2 in it but my funds are lacking!!

not lacking, just dont see a point in spending 5k on FI or 4k on a cammed/milled head 6.2 :x

Pretty standard stuff oughta get ya there.

It wasn't a NNBS but when I had my 04 GMC Sierra CC, 5.3/4-speed, I was running 14.2's in hot weather. I would have been real close to 13's in cooler weather, and one or 2 mods from being there all the time. It was just basic bolt-ons, LT's mild cam, 2500 stall, 3.90's etc....

im 14.4 @ 94.89mph in 60* weather an i still
have 3:42s an street tires
5.3/60e
TRUCKSHOP tune
Pacesetter LTs/OR y pipe
Magnaflow 14" round muffler
Circle D 3200/Vette servos
4" CAI
90mm TB
UD crank pulley
3:42/G80

i run full weight, gas tank full or almost full.

what gave you the best gain?

probably stall or tune...
