Hi Nick, Welcome to the site!
There's been more than I can recall.
A Site search will get you info. I do remember a recent thread describing removing the front crossmember, and dropping the motor/raising the body to R&R the motor.
Only done it to a 70 C10, 292 out, 327 in. And to A '65 Impala. 283 out, 250 !6 in. Lol.
