Well finally after getting my 5.3 about a month and a half ago, i got this whole week off from work so I can get started on my swap. It's going to take me a while because I work saturdays now, but I'll try to document everything I can as I go. Here is what I've done so far:
305 TBI/T-5
Spohn K-member

Looks like it should be pretty nice! Part of me kinda wishes that I could've gone with a tubular K-member...
Thanks buddy! Yeah suprisingly, the spohn k-member went in like butter without any problems. My main concern now is, I put the 5.3 in the other day and the front end of the car sits WAY too high. But I also dont have a transmission, front engine accessories, etc. in the car yet so, I think that's why it still sits pretty high. And I just put a set of brand new Eibach sportlines in (BTW I am using the stock control arms and I didnt have to use a spring compressor to put these springs in suprisingly) and I have'nt given them much time to settle. I am also using the thin rubber isolators that came on top of the front springs, idk if anyone else has this setup but I might try pulling those out to see if there's any difference in height. I will post pics of the 5.3 in the car soon.
Ok guys finally got some pictures of the 5.3 in my car now.
As you can see, there is a block of wood holding the driver's side of the block in place. I am waiting for GMPartsdirect.com to ship my order, I ordered my other engine mount and I ordered a bunch of other stuff like intake bolts, plug wires, water pump gaskets, etc.
Even with the Eibachs I'd expect it to end up as high as before, the weight you're saving with aluminum block and heads where you had iron, the tubular K, and the plastic intake where you had aluminum. Be sure to relocate the battery to the rear of the car!
Man, the more I see of the painted intakes, the more I like 'em! Just not sure what color would work with my car & not look garish...
lol I love the look of painted LS series intakes, mine had ugly markings on the top because it was pulled from a car in the junkyard and I could'nt wash them off. I went onto ls1tech.com and found a write-up someone did, it actually helped out alot! and it was pretty easy.
Ok finally got my parts in last night from GMPartsdirect.com, I gonna try to put them in Monday since i'm off. I have a question to ask though, can I use the starter from the 5.3 motor? or do I have to use the F-body starter since i'm running the T-56?

Thanks in advance, Dan
You bet. I used the 5.3L starter on my 5.3L, my LS1 and my 6.0
Lookin good! Only a year ago i was in the same spot as you, with the same displacement!
Thanks alot for the help guys, I do however have a few more questions. Are you guys using the 4th gen power brake booster hose? If so, where in the hell do I get a hold of one of these!?!?!?! I have looked everywhere! also below is a diagram of the LS1 intake. Obviously the brake booster goes to number 2, but what goes to the number 1? I do have two vacuum lines coming from the inside of the car, I'm guessing these are for HVAC? If so, is that where these go?
Thanks shel, Guys just a quick update, I got a box of parts from gmpartsdirect.com last week. Its just little stuff but i'll post the part numbers and the descriptions of the items I got. Just to let you guys know, If you want to buy new ls1 clamshell motor mounts buy them through gmpartsdirect.com. They were only $50 each while all the other companies are selling them for $80 each. Also my wiring harness should be in sometime this week, and maybe Friday I'll be able to get all my front engine accessories.

12495519 Z06 Spark plug wires (these do not fit our 5.3's so I had to sell them)

here's the accessory drive kit I am going to buy from gmpartsdirect.com, they say it's a cts-v kit but it looks very similar to the LS1 camaro kit. Hopefully it will work and i'm not pissing in the wind on this one.
Stuff I still need to buy:
T-56 approx. $1500
headers $800
front engine accessories $750
fuel psi regulator, fuel lines, fittings $300
clutch $400
LS1 clutch hydraulics $150
water pump $200
starter $200
throttle body (used) maybe $100
fuel injectors (used) maybe $100
LS1 computer (already tuned) $130
Total = $4,630!!!
BTW If anybody wants to know, I bought my oil pan, windage tray, and pick-up tube on gmpartsdirect.com. The oil pan comes with the oil pan gasket, it is riveted to the oil pan. Also these newer pans use an AcDelco PF48, I thought it would use a 46 like the truck oil pan did but it does not.
Stay tuned, I will take more pictures and keep updating!
Thanks, Dan

Well guys I went ahead and ordered the accessory drive kit through paceperformance.com. I'm kinda nervous because I haven't found anybody else who has bought this kit for the third gen camaro, the company's return policy says that I can return it within 15 days so it's not all that nerve-racking. This kit was $785 shipped to my door, I really hope this kit works. My biggest concern is that the steering arm will hit the alternator, Although this kit looks almost identical to the f-body accessory drive setup I am just not 100% sure. There are pics below of the f-body setup and the kit that I bought (supposedly 2006 CTS-V setup.)
you should be able to use the ctsv set up as long as you have the right alternator. tensioner etc.
I sure hope so, I think on paceperformance.com it says the kit utilizes the 1997-2004 Corvette components so I hope it works. I guess I'll be the guinea pig for this kit and I'll definately post pics if it works.
wow, looks good man. Did you decide to not use the tubular a-arms?
Well I kinda just wanted to do the minimum for right now so I can run this thing for a little bit, but I am definately going to get the spohn a-arms in the future.
yeah, I hear ya.. save some of your money for that tranny haha. I picked up a 30,000 mile t-56 from a guy on ls1tech for $1500 shipped and you can find'em on there for that price or cheaper all the time. Car looks good, keep the progress pics comin!
Well guys, bad news on the accessory drive kit. It's on it's way back to pace performance, I was kinda frustrated with it and didn't take pictures but the alternator was a little bit bigger than I thought so it was hittng the pittman arm, and the a/c bracket would not go in either as it was hitting the steering components as well. Now back to square one with the accessories, I am gathering up an f-body accessories list and in the mean-time I recieved my wiring harness from ls1wiringharness.com. Also I should have a computer coming in here pretty soon, I really have'nt got a whole lot done to the car as my mom kicked my car out of the car lol. I'm doing my car at my parent's house because I live in an apartment and I can't work on it there. Should have some more updates and pictures coming soon.
If you still have the truck accessories goto kwikperf.com they have brackets to adapt the truck accessories to work, if you run the a.c. it will cost about 500 if you dont only 300.

I will have some pics going up tonight to update everyone with the stuff i've been doing. I do have 1 small problem, On the C100 diagram I have there are two wires that say "Fuel Control" which one do I use? I have a feeling it's supposed to be the red becuse I have it hooked to the tan/wht right now and th relay clicks but no fuel pump.
Ordered F-body front engine accessories from Gmpartsdirect.com
Here is a pic with the accessory brackets, tensioners, pulleys, and bolts. Still need to get the small alternator bracket and another long bolt for the alternator

The front end still sits kinda high, maybe when I get this thing done i'll call eibach and see if they can make a set of custom springs for the front. I've got polished Hawks LSX swap headers coming soon, and I should be able to buy the T-56 next month since I get 3 paychecks! Woot! I also have to get a 255 LPH in-tank fuel pump, fuel psi regulator, fuel lines, radiator, radiator hoses, fans, power steering pump, and some sensors here and there.

Sorry guys, this time of the year is pretty hectic on the wallet with christmas coming up. I just bought an MN12 6-speed form a 2006 GTO a few weeks ago, I am about 75% done. I can start the car up right now but it runs rough because I don't have a MAF sensor on it yet. I'll post some pics of what I've been doing this weekend.
Quick question, does anyone know what this hole is for on the passenger side of the block? I believe it has to do with the coolant but i'm not quite sure. Thanks in advance
ganna be keeping an eye on this thread. im planing for the same build here very very soon.. also where did u get your ecm that was pre-tuned and what injectors did u use?? part numbers? my motors ganna be out of a 2000 silverado. and i wanna get all or atleast 75 percent of the parts needed before i even think about opening my toolbox because i want it to be a 3 step process.. pull, clean, install... so any info will be helpfull. thanks in advance

Sorry guys I have'nt updated in forever so i have quite a few things to go over. Below is the MN12 transmission I bought from a member over on LS1tech, It came from a 2006 GTO with 10,000 miles. The guy I bought the transmission from changed the cup out so I could mount an F-body shifter, The shifter BTW is a Hurst shifter.

I plan on using 4th gen brake and clutch pedal setup with my swap, so here is the pedal assembly I bought on Ebay for $50 shipped
I also went ahead and bought the tubular front A-arms from spohn
I also bought an adjustable panhard bar from spohn since I put sportlines on the car and I need to center my rear. Also bought rear LCA relocation brackets, I will get some pics soon.
Here I went with a Turn One INC. aluminum power steering pump pulley, The power steering pump itself was bought at Autozone.
Here is the radiator I bought, Its a 93-97 LT1 camaro radiator. I also bought the LS1 dual cooling fans off ebay for around $100
And finally, here is what the engine looks like now. Still have to fix a few little things here and there, I am also in the process of trying to remove the 5.3 crank pulley. I have a brand new F-body crank pulley to put on, then I can throw the belt on, fill with coolant, re-check some things here and there, then I might be able to take this thing out for a drive.

Planning on getting the transmission in on Monday since my Dad and I are both off.

Part #11588949
Here is a VERY good website for finding exploded diagrams like these and part numbers:
