I use some thin wire and ran it as a belt. Should work ok. fits right in the grooves on the pullys.
This engine I did without a transmission - the amt fairlane kit has an automatic and a manual so one of those should work. But I have seen the same engine printed with a transmission as part of it.
This is the second 3d model I have used - the first one being a BRODIX v8 in a 57 chevy.
They all come in handy :-)
