Welcome to the site!
The 5.3L is a motor than can get into the 13s on bolt ons + cam. With those mods and spray--you can get into the 11s.
yea i was runnin 13.669s with my 01 same motor but im wonted to brake 12s with out spray so i was thinkin a head swap would be in order i have already looked into an ls6 intake swap i no that would help me in the higher rpms but thanks for your input no one is replying to this thread ha ha
You could by my short block and have it bored and stroked.
Keep the 5.3L. Do a TBSS LS2 intake, get some 799 heads and have them ported and polished with a 3 angle valve job. With the LS2 intake, you will have a 90mm TB. Of course, do headers, pulleys, a sick cam, a stall, and tranny upgrades.
its all in order thanks very much for the input but how about the throttle by wire this is my first trip down that rd. do they make a 90mm etb
thanks again for all the help
Yes--they make a 90mm DBW TB...
what size cam do you sugest with ls2 heads
799 heads....5.3L... You gunna have a torque converter?
work over the 5.3 heads. youll lose compression with the ls1 heads.
yes something mild like a 2800
tx what all bolt ons do you have thats putin you in 12s i couldin manage to go faster than 13.669 with my orange truck and i thalt i had just about everything bolt on wise
LS1, Patriot stage 2 heads, 226/226 112 cam, 4.10 gears and a converter. hoping to hit 11's with the new 231/239 111 cam and have solid 11's with a ported fast 92mm..then im curious to see what it will do with the nitrous.
thats un real fast ma for the work done nice job
Just have the heads decked a little. Shave them down to get back to the compression level where you want...Quote:

not if he has them milled..... since hes already having head work done. it would be worth in IMO
so your sayin get ls1s and get them shaved to match or re work the 5.3s
thats pretty good what your truck ran,what did you do to the motor and what was done to the truck if you dont mind me asking
ram air hood role pan 3/6 drop 20s ps2 tv..... ls6 intake k&n cai lt headers off rd y pipe flow master with turndowns malory coil pacs air aid spacer slp fuel rail 42lbs injectors built 4l80e by a locale drag shop and tuned by rwtd dyno tunes built rear end with 3.73s and true locks cowl tracks 90mm tb and bosh indexed plugs and the heads wear just ported and shaved i think thats it
no thats pretty good,you still got stock internals and stock displacement,you ran that time on the 20's i didnt know they made cal tracs for the trucks thats cool i got a set on my nova m/t radial car
i ran the 13.669 on some 18 in m/t with hoosler slicks the fastes i ran with 20s is 13.9 cuz i spun thru 2nd and yea they don really help that much the big thing is getin some wait in the back i had 300lbs in my bed
