L92 performance mods. Need help I have a 2007 escalade and was wondering what you guys would recomend for bolt on performance parts. I understand the l92 heads are great but have been reading that they flow so much better with a cam. I know I have vvt so what would you guys recommend for a cam that will give me more power, nice lumpy idle and be smogable as I'm in Cali. How about the intake? Should I go with an ls3 intake or one of the FAST units? If I do will I need to relocate any of the front accessories? And lastly headers, do I really need long tubes? What brand is good for smog and best performance? Thanks in advance guys!
Call Mast motorsports. They seem to know the most about these engines. I would think short tube headers , cat back or just a muffler ,and a small cam would help. On the other hand a good tune would help by removing all the torq. mangement and stuff like that. I know my 6.0 2500HD is a dog with the stock tune. A torque convertor would help with off the line power.

As far as intakes go the only other intake I would run on your engine is a stock LS3. The intake you have is a really good intake but most people change to the LS3 for aesthetics. The FAST intake is great on 427 cubic inch and larger engines but we do not see a gain on LS3 engines even our 416.
We recommend long tube headers with at least 1" 3/4 primaries. You can get away with a good set of shorties without sacrificing too much power.
Let us know if you need anything else!
