Default throttle body question

I did an LT1 intake swap on my car and have a holley commander 950 ECU. I was wondering when buying an aftermarket TB do I get the one for an LT1 or an L98 (if I get a Lokar throttle cable and the required sensors)? What's the difference?

Doesn't matter.
Use whatever TB that has TPS /IAC connectors compatible with your wiring harness and your stock accel cable to make swap easier.The LT1 sensors have different connectors and cable hookup to TPI TB's
If you end up with a LT1 TB then you can get adapters to change to the TPI style connectors if that is what is on your existing harness
