This might be a good start for a custom pan: http://cgi.ebay.com/ebaymotors/Dry-sump-racing-oil-pan-Fontana-Ford-351-Cleveland_W0QQitemZ270127371140 It looks like it was converted to dry sump or maybe wet sump with a single stage external pump? Someone who wants to do some fabrication might get a really cheap pan out of it. Ken
