K, I merged you 2 identical threads and put it here in the racing section....

 

My buddies truck is a 2000 ecsb 4.8 with a 212/218 with pacesetters, tune, dual flowmasters and with a 100 shot he walked away from rcsb 5.3 supercharged joe gibbs trucks.

 

ill spray the house down if someone talks **** i got a extra motor lolive been told them bottom ends are goot till 6600 rpm so if i get a cam it needs to pull till atleast 6300

 

Mine goes to 6700 almost daily

 

I think mine would pull a 13 if I added lower gears, locker and a stall. It would be close. Throw a cam in it and I know I would.

 

those bottom ends have gone past 7500 makin 700hp

 

6750 here

Every truck responds differently to mods. TxSilverado when his truck was full bolt ons with a tb converter and 4.10's he ran a 13.9 or 13.8 with some weight reduction... it was with a 5.3l though.

Even though i have a rc i pulled off a 13.9 full bolt on (minus pulley) with a 3k stall and 4.10s with a crappy 2.0 60ft.

Just put the parts on and see what it does

 

damn scott your going to 6700 daily maybe i need to raise my rev limiter cause im only at 6100

 

Thats what I said too. I had ended up bumping up to 6400/6300

 

hows the power since you raised it
