05' 5.3L Looking for big power
I am looking for opinions and suggestions as to what I need to do or buy.
-Supercharger (brand)?
-Headers
-Injectors
-Exhaust
-what all internals need attention on the engine
-transmission upgrades
-heads
-anything else that I have missed
Thanks,
Brad
The problem is the more power you have with smaller displacement makes it harder to keep good street manners. But if you have to do it with the 5.3L, you're going to have to go FI. You will have to do everything on your list, and then some. But like I said, if you're going to have to get forged internals, why not just put an iron block 408 in there? You should be able to make the power a lot easier that way. Contact one of the sponsors on the forum (ie Texas speed, vengeance racing, etc...) and they can help you out.
