Thread: 5.3 V8 and 3.9 V6, any high perf. goodies avail?

I've decided to see if finances will allow picking up an '06 or '07 Impala instead of going with an '05 Supercharged 3.8 Impala. I know what the 5.3 is capable of bone stock as I drag raced my '07 Monte SS at the local track. I figure the Impala should be damn near as quick even though it may weigh a bit more. Are there any aftermarket "goodies" available for the 5.3 yet?
Also, anyone drag raced an LTZ Monte or Impala? I know they have 240 h.p. same as the supercharged models but not sure about the torque output. I figure they should do low 15s in the 1/4.

from what i've heard from some of the gxp owners, there isn't much of an aftermarket for the 5.3. transverse mounted V8's aren't that common, i'm sure there could be improvements but there isn't much of a market niche like there is for some of the V6's.

Basically you can do small flow mods for the LS4 or drop a **** ton of money on a turbo kit.

3.9 L high value? No idea on that one. Can't imagine theres much yet.
