a year ago at a swap meet in milwaukee i bought a welded sheet aluminium oil pan for my 470. the seller said it was a ed hamburger unit but there were no markings or tags. i did a web search but the closest pan i found was one that 440 source had that was kind of like it. seems he did alot of cheby stuff. i cleaned it up and had the external pick up hole welded up then knocked in two holes for a swinging pick up. i may use it, maybe not...
