I went back and forth from th350 to Muncie a few times in my camaro it's an easy swap as long as the 350 is a short tail. And like Special K said either bell will work,but you want a big block bell if you go with the aluminum car type bell. It's also the same as a newer 73 and up from a pickup or Chevy van. I say this because if you use a small block bell from a nova or camaro or something similar you can't use an 11 inch. Clutch. The bolt patern is the same on both but big block the bell is bigger around the flywheel. I'll post a few pictures later so you and anybody else can see. You definitely want the big clutch. I set my Camaro up like that SB 350 Bb bell 11 inch clutch and pressure plate M20 Muncie . Used to chew up clutch disks with a 10" now chews tires instead.
