82 Vette LS Swap

Ok; I am in the middle of restoring my 82 Vette and have been thinking about putting a LS Engine into it. After reading all this thread I have a couple of questions:

Sounds like the LS1 F Body is the way to go for me.

1. Can I use my Factory Tranny?
2. Do I have to change anything from the Tranny back?
3. What kind of Changes do i have to make to my Gauges?
4. And can you give more detail for the Electrical Harness?

Thanks Bobby

1. yes you can use your factory tranny with an adaper.
2. Most likely not. there are a set of mounts that will put the LS in the factory SB location.
3. If you use your stock tranny the speedo won't be a problem. The tach can be taken care of with a Dakota Digital signal converter. As for the rest of the gauges you will need some adapters for the LS block but S&P has them available.
4. If you are not electrical savvy send the LS harness to John at http://www.speartech.com/ and he will take care of you. It will be very easy to hook up.

let me know if you have any more questions.

Josh, headers are most definatley in the plans and as far as a pan my main thoughts for using the Batwing is for the ability to maintain oil in the sump during hard cornering.

well I know that the batwing pan won't work with the stock power steering, I am not sure about the rack. There is a company that makes a really good windage tray for the F-body pan that will take care of the sump issues. I just don't think that the batwing pan is a very good option. I know of alot of Z06 cars that have oiling issues on the track...

Since you are planning on the headers, use the speedhound plates or I have a set of dual position motor mount plates that put the motor in the stock location or moves it forward 1"

Accessories: do you plan on using the GTO accessories? I have a set of A/C brackets that will allow you to use the R4 compressor on your motor so you can use your stock A/C lines.

I also have a good solution for the tranny crossmember if you are interested.

Definatley interested. Like I said I am in the process of researching the project. I would think that if possible I would want to set the motor back a little if possible and maybe even lower it some for weight distribution. I would really like to set it up for handleing make it track worthy but hardly ever track it. As far as the accesories I need to figure those out I'm not even opposed to running something like the March set up if neccesary.

I have differential, suspension and, brake mods planned I would really like to get some major power issues done too.

Ok, here is my opinion:

Mount Plates: Speedhound or My dual position plates. Vetteworks has an adjustable set but they are still being prototyped. These will put you as far back and still leave you alittle room at the firewall. Also you will have to modify your shifter to get it to come up through the stock console. You can get a six speed plate from Keisler, just call and ask for it, it is around $25 See attached pics.



Tranny Crossmember: Use a bowtie overdrives 2004R tubilar crossmember, and have them extend the perch 7/8"

Accessories: Use the F-body accessories and my A/C brackets, this will leave your factory A/C lines and controls in tact. (See my pic on the first page) I can get you very very good prices on the brackets to hold the alternator and power steering pump. You will need to modify the water pump (See my pics on the first page in the waterpump section.) I can do this for you if you don't feel comfortable doing it.

Oil Pan: use the F-body pan. You can get a complete pan for around $260, still looking for the link for the windage tray...

Power steering: Go with the Steeriods http://www.vetteworksonline.com/steeroids_corvette.htm or the Rack attack from VBP. http://www.vbandp.com/detail.aspx?ID=1100

Brakes: if you want to convert to Hydroboost let me know.

GM LH8 LS Conversion Oil Pan

Has anyone heard or used one the Oil Pans from BRP Muscle Rods? Here is the link:http://www.brphotrods.com/Oil%20pan.html

They show the F Body and their GM LH8 LS Conversion Oil Pan; which seems to be designed for just what I am doing, putting a LS into a 82 C3.

Like to hear any feedback.

Bobby

Josh sounds like a plan. I am thinking Hydro Boost too I'm torn on my brake options. I know that I am going to get at least in the 13" rotor area so that makes Willwood, Brembo, and Baer part of the conversation. I absolutely love the way the New Extreme 6S Baer calipers look though.

Bobby I have that pan listed on the first page. It looks to be the smallest pan as far as capacity and will fit with the steering dampener and a rack with either set of mount plates, however the sump is deep like the truck pan. If your car is lowered, it may not be the best option.

I know over 20 guys that have done this swap in multiple ways. The F-body oil pan is the best option.

I can hook you up with a guy that does hydroboosts. price is around $150. Very good upgrade for your brakes.

Here is an option over the Wilwood, Brembo and Baer stuff. VBP makes a C5 brake conversion kit for the C3 vette. Order their kit without the calipers and get the C6 Z06 6 piston calipers. They are a direct bolt on to the C5 brackets.



I was going to do this but I have stock wheels. for now...

I like this idea. I have not even checked into their brake kits. I have been running the stock brakes since I rebuilt the calipers with O-rings years ago. I may have to look into this a little closer.

They have a kit that does a swap for the front brakes but is there anything out there for the rears? I did a C5 conversion on my Blazer and love the brakes (I did front and rear) but I wouldn't want to do a conversion unless I got rid of all 4 of the boat anchors. I also think 13" all around is nice, 14" is crazy but.... would look freaking ridiculously HOT. 18" wheels and a 14" 6 piston FRONT 13" 4 piston REAR would be the shizz.

you do realize that 80% of your braking is in the front? And the stock calipers on the Corvettes are pretty dang good. They are 4 piston front and rear. I have a set of the VBP stainless sleeved ones, hydroboost, and cross/drilled slotted rotors and my car stops on a dime.

Yes I do realize that but, the whole unsprung weight issue and also the technology differences and I hate to say it, but they are kinda ugly. lol

Someone needs to make a kit to mount C5/6 brakes all around on a C3 that would open up some great options. I'd be all over that.

you could do the Z06 out front and do the SSBC out back?
