You are way ahead of us kit builders as far as dedication is concerned in addition of everything else. I have watched several Easy builders over the years, and at my visit to Ernest last Christmas, I realized again how much difference there is between kit and plan when Ernest explained to me how he managed to manufacture SS channel because it could not bought anywhere. I think plan-builders are the creme of the experimenters community. FWIW.

Your oil cooler setup looks a lot like my radiator duct. Buly On Jun 27, 2006, at 9:37 PM, Ernest Christley wrote: > There hasn't been many building reports lately.
