What do you guys think?
not sure were to post this guys.. lol
Well i have a 99 RCSB 5.3 Silverado..
Looking to see a good estimate on my quarter mile time..
i have long tube headers.. Cold air intake.. 3in full exhaust.. no cats in to 2 dumped Bullet mufflers... Black bear tune.. Transgo HD2 Shift kit.. 2nd gear vette servo.. and 4th gear billet sonnax servo..
i know a bunch of factors play a role in my 1/4 times but im just wanting to get a good estimate on what it would run with the mods..
Helpful note is i ran the truck stock on street tires and it ran a 15.7 at 87mph with a 2.3 60ft.. with 16in eagle alloys with 285/60/16 tires
i then ran it with 20's on street tires with just a black bear tune and got a 15.7 at 90mph with a 2.6 60ft.. traction was a issue lol boss 330's with 275/45/20 tires
all the help is appreciated!
Thanks mike.

Not necessarily, drove my buddies 5.3 rcsb with just bolt-ons and 4.10 gears to a 13.7@99mph all stock internal. It can be done with tires and gears.

You should be mid to low 14s I have a 2006 rcsb 373 CAI, predator programmer, no muffler, vette servo, with no bumper spare or tail gate i ran 14.7s all day at 92 mph. The weight reduction helped me on the big end but i spun on the launch. You can run 14.5s at least probably better. Biggest thing hurting u is gears right now
