I've been having a bit more of a think about the blower option lately. A manifold for a positive displacemnt type blower wouldn't be to hard to fabricate for the LS1. I could incorperate a water to air intercooler under the blower an have a neat and tidy looking set up that would make respectable numbers.
I've heard that the roots or screw type blowes make better botom end than the centrifugal type (I may be wrong). Plus I like the look of the blower in the valey.
I've been thinking about using and Eaton

I may just say stuff the blower and fabricate a cross ram set up to free up some naturally aspirated HP. Guys are getting 460 HP out of these motors with out major mods and the stock intake manifold is said to be the weak link to making more HP. The cross ram style intake set up looks horn too. Check out the intake on the new 427 Monaro... Woo Hoo!

Plenty of time for me to dream.
