What kind of engine mods are there for a 5.4? I know about air intakes, chips, exhausts and other simple bolt-ons. What I'd like to know is are there any race heads or cams or anything like this that would give the engine a serious kick in the pants? Thanx in advance!!

 

In short, yes

If you check out the lightning forum you can probably find alot more stuff about this area (since the Lightning uses the 5.4L engine, with a S/C).
