LM7 to LQ4 swap questions

[yota]

looks like im just going to be swapping my 5.3 out for my 6.0 lq4 myself due to various reasons... the main reason being that i just found out that i have to move to new york next month i'm planning to do the swap the weekend of oct 1-2, probably starting on it that friday morning actually, so i want to start brainstorming and knocking any little snags that might come up out now, before i get elbow deep in this and find out that i'm in trouble lol

basically, i have a 2001 tahoe with the 5.3/4l60e... swapping in a 2001 lq4 out of a wrecked 2500hd... the donor engine is complete from throttle body to oil pan, including everything except for the coil packs, accessories, and starter... i'm assuming everything is a direct swap and from everything i've read seems to point to this being plug and play, just like swapping in another 5.3... is this correct?

other parts going in at the same time include a 2800 stall and a set of OBX stainless headers and y-pipe... anything i need to worry about with these parts? or is it just bolt them in and you're good to go? i think i remember reading something about plug wires with the headers due to the "hump" in one of the primaries... anyone know if this is an issue and what i need to get to make everything work if so? also, should i put wire socks on the plug wires or should they be fine without?

the only other thing i think i'm missing is that i'm sure it will require a tune to run optimally... will this thing still crank and run on the stock 5.3 tune though?

also, anyone who wants to help out and lend an experienced eye to the project is more than welcome... i will be doing it at the hobby shop at the weapons station hopefully and will offer a nice steak dinner to anyone who wants to come out and lend a hand

thanks in advance
