360 transplant
I am working on this very swap myself, only I think I am taking it to the next level, granted my car is a 72 Swinger and is a small block car, Rumblefish didnt leave much out. Standard small block torsion bars ar .870, option are .890 and .920.
My donar wa sa 94 van, I gutted everything, and I mean everything, and intend to graft the entrie wiring harness into the dart, and even use the factory electric in tank fuel pump, with some obvious fabrication.
Biggest issues are getting the trans to fit properly, thus requiring modification to the floor and trans cross member.
