Has anyone from the site contacted Callaway Cars in Old Lyme, CT? They have done a lot of hi-po LS1 speed work with Holden in Austraiia. They also told me in email they already have some packages to "elevate" the stock engine developed. I know these folks come highly recommended and would make a great addition to the site sponsors list.

Don't hold me to this, but rumor has it a few of their employees have been known to :drink: :drink: :drink: :drink: :p

Being a GM approved (or whatever) supplier, Callaway was contracted to build the top-of-the-range 300kW (400 horse) LS1 that is used in the Aussie and New Zealand HSV GTS sedan and coupe. Without going into specifics, CW machine-ports the heads and installs a different cam. These engines are shipped to Aus and are factory-installed into 'core' cars that are destined to become HSVs. You may not be able to get the exact HSV bits (the IP belongs to HSV), but I'm sure Callaway could be able to do something for you!

I know this is an old post but I just now noticed it. Back in the late 90s, everyone was selling shorty headers for the Impala SS. I wanted long tubes. I contacted Callaway and was very specific on what I wanted. I ordered the long tubes at a price I felt was way too high. After waiting 3 months, they sent me a set of SLP shorties. I returned them and waited even longer for my refund. No more Callaway for me. :banghead:
