Does anyone know where i can get a motor mount kit for putting a v8 302 into a v6 stock mustang of year 1983. What else do i need to do? It has an automatic transmission

 

any 302 motor will work on the V6 k member, vert mounts are better than the standard mounts. IMO I would ditch the 7.5 rearend and look for an 8.8 unless you are keeping the motor stock or very mild but even then the 7.5 has it's weakness.
