Ok so I was gonna go with Allen's new kit, but the trucks a DD and honestly I can't afford to find all the weak links to have a reliable 500 horse DD. So plan B: Cam and bolt on 5.3

Leaning towards a GMPP cam, because I get a really good price on them so the Hotcam is a little small so I think I've settled on the Stage 2 Hotcam specs are:
227/239 @ .050
551/551
108 LSA

Here's a video clip YouTube - gm performance parts stage 2 hot cam

So my question is, is it too much for a DD?
