426 hemi into 67 barracuda

The hemi blocks use their own mounting ears and standard big block brackets don't fit. The k frames are also different. There was an aftermarket block from mopar performance that used standard big block mounts. If you don't have an engine yet you may be able to use a big block k-frame with one of those blocks. There are also new tubular k-frames that will mount a hemi in a second generation a-body. The hemi is a tight fit and will take some custom clearancing to make it work.
