I'm putting a big block in my 73 dart and the mounts are impossible to find right now. There are people on here who can make a mount for you, or you can do a motor plate. I elected to do a motor plate. You can also find some DC K members that are for big blocks, or you could have someone modify the one you have.
I ultimately elected to go with a motor plate because I might race this and wanted a spot to mount the electric water pump and fan. It was just easier for my set up. You can get motor plates from Mancini or a number of other dealers.
