Oh ya and n/a my built 4.8 put down like 264rwhp and 250rwt. This was one 89oct and with a 8.5-1 compression engine.

 

yea i got a LQ9 block at home but i think im gona save it for my next f-body and just stay pretty miled on the the truck. but this stock 4.8 isnt doing it for me

 

My buddy just got a custom tune at Synergy today and he put down 260rwhp,274rwtq in his 04' 4.8L 2wd with an intake, TOG headers, stock exhaust with a flowmaster 1ch muffler. The cam would really wake it up. The lil 4.8Ls can be strong

 

thats sweet give me alot of hope to break 300+ with just a 02+ LS6 cam

 

do not mean to hijack, but is it fairly easy to break 300 rwhp with a 5.3?

 

Yup! Cam, LTs, Intake, Exhaust and custom tuning will get you there pretty easy.

 

yea it should be, i mean i came from a LS1 world where my 99ta was a cam only w/full blot ons and made 414 threw a 6 speed, it was a pretty small cam too, so this truck stuff is pretty easy to me just wasnt to sure what a 4.8 would do with just some minor mods and a mild cam in my mind.

 

yeah i have help build a few ls1's and converted my 94 ta to 6.0 6 speed, so the truck stuff seems quite easy. just my 5.3 is in a 81 c10 swb.
