5.3 67 chevy engine swap

[itchy]

Anyone ever done a 02 5.3 chevy engine/trans swap. Its competely hookedup except for the engine wiring harness.
I plan on using the orginal type 67 chassie/body harness. But I need 5.3 engine/trans. harness ideas. I know summit sell a intake/carb setup for that engine, but thinking the fuel injection would be better. I have seen 5.3 harnesses at the local salvage yard, but gee ! I can't need all that. Any ideas ? Thanks !
