Not advisable....
The reason being that the BBC TB has 50mm bores and 80 or 90 lb injectors vs. SBC TB 46mm with 40/55/64 lb injectors depending on engine size. You may be able to get 454 started, but the moment you ask that 454 to deliver power it will lean out and fall on its face. IMHO the swapping harness connector ends is straight forward, except for IAC which may require pin swapping. I believe that I have a set of notes related to this issue. To me revamping harness to mach sensors (2x) is not that difficult.
Take a look at two TBI (SBC/BBC) setups first before jumping to any conclusions.
