Slp catback? I want to see a video of it! my buddy has slp dual on his trans am and its hella loud I love it.

On to your question... I would recommend ls6 springs and better rods. I was planning on getting ported manifolds as well. I dis research comparing headers to em and from What I understand you get same amount of power but ported manifolds last longer then headers.

Between milzy and wot.. milzy seems to have alot more stuff like race block with forged internals, powder coated motors with Cam options, and a 4t65e tranny conversion kit with stronger internal options. Idk how good service is thru milzy or wot because I've never bought anything from them yet.

When I build my car I'm Probably going with milzy because they have alot more options for our cars it looks like. I'm not saying either company is bad! Just saying.

Also I don't think you need to fabricate anything for the Cam it should be just like an OEM Cam but with more power offered.
