Where can I get cop car TBI injectors?

I think the cop cars had multi port injection.

They had TBI with 65 .lb/hr fuel rates until the LT1 which has sequential fuel injection which is a port fuel system.

Did the LT1 have multi-port injection? I though it still had throttle body? As for pre-LT1, the L05 used TBI.

Found them @ FIVEO motorsports
