Alright guys,

I know this has been beat to death, but in all honesty I've done ton's of searches and haven't come up with any definite answers. So any help is greatly appreciated. I have a bone stock 98 Z28. Car is 6-speed with 55k. I have already ordered most of the supporting mods for a head/cam setup. Car will have full exhaust and intake.

I'm really looking for good low-end to mid-range power. Don't really care too much about 6k plus because I'm rarely up there. I also would like good street manners (aka no huge cams). I would like to get over the 400rwhp mark, and I would like to stay away from flycutting.

So my question is, what Texas Speed PRC head/cam combo should I go with? As I understand the 2.5 5.3 heads are good if you plan on running n/a, and the LS6 are better for the other applications. Can I expect more power down low with the LS6's or the 5.3's?

Also, I'm wondering if a fast setup would be overkill for what I'm looking for. Can I get away with using an LS6 or aluminum manifold? Or should I wait for Weiand's new street warrior?

Thanks for your input everyone, and thanks for taking the time to read my post.

Call jon @ tsp, but i think a tsp 224r, with the 5.3l stage 2.5 will get you around 420 with the ls6 intake. Would be a good street set up.

Yeah a 224 cam should get you there. I put down 402 through an auto with the 5.3s and a TR224 and a .04 head gasket.

I would recommend the TSP 228R cam. I made 400rwhp with it cam only, plus it has a good driveability and a nice lopey idle. I can't recommend a head choice because I am trying to decide between the 5.3 Stage 2.5 or the LS6 Stage 2 head myself. I did see one post were a guy made 445rwhp & 401rwtq with the PRC 5.3 Stage 2.5 heads, TSP 228R cam, and a Vengeance Ported Fast 90 setup with the other supporting bolt-ons.
