The G-Body Swap Thread
http://www.nordskogperformance.net/p...ail/dp9255.htm
I plan on having the lsx harness modified by someone else as I dread working with electrical wires, i dont have the patience. I planned on using HP tuners, but how is EFI live, never heard anything about it. Did you mount that fuse panel underdash or underhood? Am I going to need to "tap" into the harness under the dash for anything?
So I just looked up EFI live, and basically it allows you to delete the maf and tune the vehicle using speed density mode? How does this benifit over a maf read system? As you can tell I dont know much about electronics and tuning just yet.
1. what are the options for getting the TV cable from a 2004R to interact with the electronic throttle on an LS-2? should the TB and computer be LS-1? other options?
2. with JohnB's mounts, is it possible to notch the crossmember to get the stock oil pan and compressor to fit? it seems like this would be an easier option??? (get some steel welded back in for strength)
i plan on starting the swap in a couple of months. i'd like to get all my parts put together ahead of time, and have a clear understanding of all the obstacles ahead.
can anyone reccomend a salvage yard or dealer for used corvette drivelines? Also, if I came accross a LS-6 is this a better or worse option than the LS-2???

I'm about to undertake a 5.3 swap into a '79 Malibu for my 15 year old son. I want to use the 5.3 because it is cheaper, and I'm not interested in high HP, since my 16 year old will be driving it. It will be faster than anything I had when I was 16!!
I know a few of you guys from my website, and it's good to see some familiar names. Anyways, I plan on having a lot of questions, since this is my first experience in retro-fitting an EFI application into an older car. I'm starting to document my conversion, but we are very early into the game.
My main concerns at this point is what kind of problems will the 5.3L truck engine present? Such as accessory interference, oil pan clearance, best option for motor mount plates/mods. Also, will the factory truck intake clear the stock hood?
I believe I've found a complete engine/tranny setup, but want to make sure I have all my ducks in a row before dropping the cash.
Here's the link to the conversion thread I started on my site:

I have a LSx swap forum, so you guys that aren't familiar with the site should check it out so we can all help each other. The site is for all G-bodies, not just Malibu's. Thanks, and look forward to talking with some of you guys.

If you google his name he will be at the top. Go to his site and he chronicles many of the challenges you will face. http://home.earthlink.net/~bzdel/
He has a LS7 in his car now but still has many pages of detail regarding the LS1 that he started with.
He is the one that inspired me to get rid of my 3rd gen formula ( spent three years restoring that sucker..lol )and buy a Monte SS for the LS swap.
John makes a custom set of motor mounts and offers a mod for an f-body oil pan if you prefer not to notch your crossmember. I dont know the price but it would probably best to shoot him a PM as I am going to do now. ( Tax return check is on its way!!! )
Others have used his solution ( mounts or mounts with pan ) with great success.
Im assuming he doesnt advertise a price here as hes not a vendor on this site which would be a conflict of interest.
Cheers
Some of the pictures were taken a while ago while it was still a Work in Progress.

BTW, does anybody know how much the truck oil pan hangs below the crossmember. Is it unfeasible because of ground clearance issues?
I haven't had the opportunity to personally verify this so up until now I have been hesitant to recommend this but after review of the photo's below (assuming the measurements are correct and I have no reason to believe that they're not) it appears that the CTS-V LS2 oil pan should be a direct fit WITHOUT modification for the G-body!!! When I modify my pans, I take out about 1" and this is actually tapered so that it is slightly less in the middle to match the contour of the engine crossmember. If you carefully compare the F-body pan (which I use for the modification) to the CTS-V pan you'll see that it not only is 1" shorter in length at the deep end but it also tapers in the correct direction on the sides in addition to this!
The other beauty of the CTS-V pan is that it is a shallow pan (only 1/2" lower than the F-body pan!) so that you don't have to worry about having something hit your oil pan because it hangs below the protection of the engine crossmember (remember...these are CAST aluminum oil pans which will crack or break on severe impact rather than dent!!!).
I'd hate to see someone try this and then tell me that it doesn't work, but by all indications, it sure looks like a slam dunk to me not to mention price-wise its probably about the same as a modded pan (once you add the price of a pick-up tube, windage tray and oil pan baffle).
Hope this helps!
Specific's of CTS-V pan:
Capacity: 5.5 qts
Oil pan: 12577901
Oil pump pickup: 12577906
Windage tray: 12558268 (same as Truck "C/K)
Dipstick tube: ?
Dipstick: ?
O-ring for Oil pump pickup:?
Oil pan baffle: 12577904
There are some pics of the truck pan hanging below the crossmember in one of these G-Body swap threads somewhere around here, I just can`t remember which thread.
4l60e behind a 2000 ls1 if not would the 200-4r work and if it would could i build the 200-4r to handle 500-600 lb tq
