72 Cuda-?392 HEMI
Plan to fabricate everything. My dad put a 392 in a 67 Coronet and there is nothing off the shelf. So you'll be fabing mounts, headers, etc. My opinion, pass and get something that was designed to fit. Old hemi's are heavy and expensive, leave them for the street rod crowd.
If your new to this then this isn't the swap for you.
