Jim, Dont give up hope yet. Marc and I have been chatting in the background about intakes, etc. there are ways to get low volume manifolds vs cast. I will contact my fabricator with a simple sketch for a log-style manifold for running 3 1-barrels on it to get a ball-park. The cost may or may not be within your budget, however there is still hope. Plus, I dont think Marc has posted intakes on inliners yet.
