Getting ready to swap a 5.7 into my 73 Dart Swinger

I have a 73 dart swinger going to 5.7swap it as well. Engine bay just got the 440 cleared out. And I have a 5.7 I'm ready to buy. I'm hoping the progress is being made with your swap slowly but surely. I'm not worried about the transmission as I just had to handle that same issue swapping ls3 and tranny into a 55 c10 for a customer.
