Just offhand, it looks rather poorly done. Thin stock and warping. On the other hand, Wayne Gapp had a single plane TP manifold modified by Anteau so that it became a Hilborn set-up and ran it on a Cougar he called, I think, 'Top Cat'. Since the spacing on the throttles wasn't quite the same as the runners in what was left of the original manifold, Anteau had to get a little creative with his 'Heli-Arc'. Brother Lon found it, some years later, at a garage sale and paid something like $50 for it. After it decorated the bench in the back of his garage for a few more years, he sold it once more!
