Going fast and 28s don't go together. Unless your talking about tire size. And assume your talking about the 5.3L

Never heard of a 5.4L engine. The typical performance route is air intake and headers/exhaust followed by a tune. Next is usually a cam. However, not only do you have huge heavy wheels to deal with, you also live in Californication which limits you to CARB legal parts. Not a lot you can do about that I'm afraid. You can still do shorty headers and a tune, that's good for maybe 25 hp.

My suburban has a 5.4, but it got bored when I built it. That .1 oversize is good for 150 hp, 331 CI monsta!

I've seen F-150s running LS engines but never thought I'd see a 5.4 in a gmt800/900 GM......

Why stop at 28s? Lift it and put 30s
