Hi Slowy,
Yes it is Bernie at Enklemans. He was very helpful on the phone and gave me the impression it would be relatively straight forward process. I'm not going to waste any more of my time with Colin, If he can't be bothered to return any of my numerous phone calls what hope would I have of seeing him actually complete a report on the car.
I've put the LS6 manifold back on just to keep things simple for the people at Vic Roads. I may be confidnent that it won't affect emmissions but I've got no way of proving it without spending extra on testing.
Phil N is going to try out my manifold on his motor and see if it makes any improvement over the LS2 manifold and 90mm T/B. I'm really keen to see the results.
Cheers
