Brains has a nice site and there's another one, but i can't remember the name. good luck and please keep us informed.

Brains, you're saying that a 4.6 k-member from a SN95 car will bolt into a fox body? I never knew that. Everything bolts up to it without a problem including the stock fox control arms and steering rack without any modification to the rack or control arms or steering shaft? This may be a budget alternative to the tubular setup everyone is using.
Bolts in as-is. The 4.6L stuff sits a hair forward though, so you'll need to extend your steering shaft, and keep an eye on tire location in the wheel well. My current combo is a mix of parts -- 4.6L AJE K-member, stock 1987 control arms, stock 1987 power rack, and I modified my steering shaft to be about 1-1/4" longer to fit. My wheel/tire sits about 1/2" farther forward looking at old pictures vs. now.
Oh, if you use a stock 4.6 K-member, you MIGHT have to notch it slightly to fit the corners of the pan, but its minor. You also won't have as much header clearance as with a tubular, obviously.

Well, i'm good to go now!
i just bought LX1's car over the weekend and now own an LS1/6spd combo, for now! 
lol. i'm actually going to be ditching the 6spd for an a-3 for a more drag oriented setup, but not to the extent that some have gone, but i'd still like to see 10's on motor & 9's on as small of a shot as i need to do it. LX1/Dan, was able to pull off a 12.5 on true street tires, not drag radials, & 3.27's out back with no major weight loss other than a tubular k-member & a-arms. it's got heavy 13" '03 Cobra discs, p/s, p/b, & a disc brake rear setup too. as far as LS1 coupe's go, it's probably about as heavy as it can get. that should give you some idea what kind of times it can run. oh, and he ran 114 mph, which is an 11 sec mph while babying it out of the hole so he didn't spin too much. but i plan on working on that a bit, short of breaking out a hole saw or buying lexan windows. i may even keep the stock hood and spend the money on other things, rather than buying a fiberglass unit and paying to have it painted. i'd like to get a V2OD overdrive unit with a .70 od ratio so i can still drive the car comfortably when i get some 28's & 4.30's. it was nice hitting 100mph over the weekend at only about 2200rpm's in 6th gear!!!
that's the one thing i would miss about a manual, but i am not comfortable racing a manual trans car. it's just not my preference. anyway, the pic in my sig is LX1/Dan's old car in case anyone recognizes it.later.

I don't think you'll have the heaviest LS1 Coupe, I'm sure that'll be me 
My interior alone is probably 1 to 2 hundred pounds heavier than stock. I went with full power leather seating from a 2003 GT, and even made the split rear seat fold down stuff functional. My goal isn't to be the fastest car, just something good looking, fun, and quicker than most.

i really want a trans brake setup, and thus far i have not seen anyone with a good setup for the 4l80 yet. plus, i can do the trans swap now and see if i will even be driving it enough to worry about it. then if i want one, i can always weigh my options later, but the V2OD is a nice simple piece that weights little.
Brains........if you want the title of the heaviest, go for it, i will not stand in your way.
PRAY HRD are you building an all out drag car or a mostly strip/some street car? a 4L80E is gonna be fun to fit in there. I was lucky and had a th400, two 4L60Es, and an old 4 speed in the garage when the 4L80E came so I could compare them all. the 4L80E is huge! and its HEAVY. it honestly feels like its 100 lbs heavier than the 4L60E.
I thought of going with a th400 for my upcoming fox project but then decided that I do actually like to drive the car on the street and I HAVE to drive highway to get anywhere. I really wanted not only an overdrive but a lockup converter. I opted to spend a little more cash now rather than buying a th400 now then selling it at a loss and buying a 4L80E later. im on a tight budget though. I may have to use the stock 4L80E converter if I can't find a decent one for under $1000
I just cant wait to get started on the project. LS2 + 4L80E + light fox =

bottom line, i don't want a 4l80e. i'm gonna get some practice in with my speed shifting and see if i can't pick it up a bit more. i'm way faster with this 6spd than i've ever been with any of my previous 2 manual tranny's, which were 5 spd's that had a very positive gear engagement (kind of clunk/clunk out & into the next gear), and stiff clutches. this one is VERY fluid feeling and confidence inspiring and before i commit to anything yet, i am going to have to go to the track to see how i do compared to LX1, who can shift pretty damn fast. if he ran a 12.5, and if i can get at least a 13.0 my first time out, not knowing the car as well as him, especially off the line engagement, i will be happy with that as a start and possibly keep the 6spd in til next season and see how i do.
ok, here is the ricer in me:
i, too, have serious plans of swapping an lq4 / t56 combo into a notch. the mechanical aspects don't worry me, as i am capable...it's the electrical stuff that worries me. how did you do the wiring, lx1? did you integrate the ls1 harness to work with your stock ford gages? i'd like to retain all of that if possible, i don't want to use aftermarket gages if i don't need to.

s346k. I used the stock pcm and wiring harness to power the motor and gauges. I used all autometer gauges so it was a little easier to hookup. However if you hook the tack signal to the stock gauge you are going to have to change to pcm to a 8cyl pulse width. The stock reading is on 4cyl because it reads one side of the coil packs. When you have vats turned off have the tuner change that setting as well. The speedo however will need an adapter to hook the cable up to. Do a search here on ls1tech and you should find the adapter.
For fuel pressure just get a ford sender and use an adapter to hook it up.
Same goes for the water temp.
Volts should be easy.
Fuel level whould still work with the factory wiring.
