318/360 production info

Keeping your converter with the OEM trans? Then for a 318, it is a bolt in. For a 360, a B&M adapter flex plate is needed. I use them without issue.

I think any engine you find in the Lanseries is going to need a rebuild unless it is a known good engine.

FWIW, a Magnum engine would be a better bet. Just swap on a carb intake.
