From Jay Brown's book (The Great FE Intake Comparo) it shows the "A" and "B" dimensions as 4.375" and 6.375" respectively for both the Ford Medium Riser and the Ford Sidewinder intakes. There is a gentleman in Mass. that has a Shelby Sidewinder installed on his scoopless ERA. Assuming the Shelby and Ford Sidewinders are the same than I would think the Ford Medium riser would fit. However, assuming the Shelby and Ford Sidewinders are the same may be a stretch. I sure hope they are as i intended to install a Ford Sidewinder on my ERA which is in production now and scheduled for completion later this year or early next year. Thanks for any experience or insights offered.
