First, you have to pick your transmission, keeping in mind that BBC will make some torque.
With a Richmond or Tremec TKO you can use standard Chevy scattershield and mechanical linkage.
If you a B/W T-56 from a 93 to 97 Camaro/Firebird, you can get an adapter scattershiled and use the "pull style linkage".
If you get one from a 98 to 01 Camaro/Firebird, it uses a different adapter bellhousing.
Good luck!!
