What Is the SFI Foundation, Inc.? The SFI Foundation, Inc. (SFI) is a non-profit organization established to issue and administer standards for specialty/performance automotive and racing equipment. What Do the Letters "SFI" Stand For? SFI was originally a foundation run by SEMA, the automotive aftermarket trade organization. The letters "SFI" stood for "SEMA Foundation, Inc." Although SFI is now completely independent from SEMA, the Foundation has retained the name SFI Foundation, Inc. but the "S" no longer means SEMA. Who Uses SFI Standards? Manufacturers of equipment are the primary users of SFI standards. Some standards are adopted as part of the rules of race sanctioning organizations. Ultimately, the consumer benefits from the program as it establishes recognized levels of performance or quality for a product. But than again my EBAY maddog racing SFI flywheel would not even fit the end of my 455 crank .I guess it would be just fine riding alone in the trunk.:af:
mad dog flex plate The one i got from mad dog fit perfect. It was solid with just the crank and converter bolt holes in it and it was made by cat. It may be possible that they sent you one for an olds 455? They have made that mistake before with a friend of mine and he sent it back and they sent him the right one.ou:
