Need help on putting 2004 5.3 vortec in 1986 c4

This is first post but glad to be in the club. I have a 1986 corvette that I am putting a 2004 tahoe 5.3l vortec in. Stock 700r4 trany. I know I need the spacer for the flex plate,I am getting motor mounts made by a friend. But I have alot of questions never done this before. I am a diesel tech and have worked on about everything but not a swap like this. I just want to keep everything stock that I can. First thing is does anyone know what intake will work on a 5.3 that is low profile and will reuse injector and truck harness. Then the other issue is of course oil pan is too deep what do I need there any help would be great.
