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.
