LOL, they move some serious air. Kurt gave me the numbers and they are sick. They are a proprietary CNC job with special attention to some areas for our application. Dealing with Kurt has been something up to this point I never thought possible, he spends a lot of time with his customers when they are at the shop teaching why he does what. Some of the projects he has going down at the shop (going overseas) make mine look like a stock block build so I have no doubts his work will be all it should.
Kurt is supposed to be the man when it comes to building high horsepower LS based motors. I remember when he was with W2W they had the first 6 sec LS powered car with Mike Moran's old "Casper" 4th gen Camaro. Sounds like your in good hands!
