Destroked Small Block?

4079144673_f0d3fa92d5_b.jpg Nascar did have some larger destroked Hemis over the years. 390 something also sticks in my mind, but that may have been in drag racing and/or Nascar.
But one of my favorite "destroked" stories is when Dick Brooks almost won a race (Daytona?) with the basically 305 Trans-Am small block in his Daytona wing car.image-jpg.jpg
