Nope...CHI is an Aussie company, as is Blue Thunder IIRC. Both have C stuff and both are great, but I've never heard of AFD. I saw a comparison of stock 4V heads to E'brocks, and the E'brocks lost, BAD. I'm not really impressed by their 420hp out of a 377C either...you can get that out of a 351C with stock heads if you're careful. I think they tried for the best of both worlds and ended up with a POS.
