about engine swap

Welcome from another 72 Valiant owner. I'm sure you'll get a lot of idea's about what options you have. This is a great site. There's all kinds of ways to go. For myself I go to swap meets, watch ebay and have a great friend that's a Mopar guy. 340's are pretty expensive around here so a 360 with a 904 out of a Newport was my choice. You need a 904 or 727 from a V8 because the six tranny won't bolt up. You either have to change the K-member or get a motor mount swap kit from TransDapt or Schumacher's. There's also upgrades to your torsion bars, front brakes and rearend. It's a great swap to do and you can go as cheap as you can (I'm tight) or high dollar or somewhere in the middle. Good luck and have fun.
