Scampi, all my knowledge comes from years of experience but you can read about these things right here on the Internet, just google Allpar or 413 hp engines.Here's on sentence from Allpar - 1962 saw a new and highly unusual setup: the 413 Max Wedge, with two 4 barrel carburetors and two ram-air intake tubes crossing each other to gain an optimum length to produce an incredible (for 1962) 420 hp.
