I cannot find any for a 385 series Ford, nor did I expect to. I have flanges, and bends, and was considering making a set, but, it occured to me that it may be possible, with a bit less time consumption, to cut the flanges off of say, a big Chevy set, and just recreate the last couple inches of primary, directing them towards a big Ford port flange. Problem is I don't have any big Chevy stuff for comparison . Anybody know offhand the Chevy port dimensions vs. the Ford? Are they remotely close? I can't find the info on the inter-webulator... thanks!
