Hi All... I just finished my LS1 install in a 79 Vette. Finished on June 5 and left for two legs of PowerTour on June 8... car ran like a champ. Stock LS1 with Edelbrock dual plane, MSD6010, and Demon 650 mech secondaries... I bolted up the Tremec 5 speed I already had in the car. This only thing I regret is that I didn't do this last year! I can help with some issues if anyone has them... when thru a quick learning curve on power steering pump and all of the accessory brackets (look at Kwik performance). I would highly recomend this swap to anyone.

Well my brother is letting me borrow it for the mean time. From his 417 sbc. I'm just going to have it probably redone by the carb shop. There shouldn't be a problem right?
idk if this has been covered but i am in the process of gathering all i need to do the ls1 conversion in a 71 nova, imma be running the carb setup which does not require a harness, but i was wondering wat tranny you guys are running, and if your running the ls1 auto tranny how are you doing so??? any info would be of help thanks.

Thats a HUGE carb.....I used a 725 on my 383, even dejetted almost 15 sizes it still ran PIG rich...
Welcome to the group! I saw your post yesterday, but I figured some of the regulars would jump in and fix you up. Since they haven't yet, I'll see if I can get you started. If your question is only about the coil packs, you can easily do what you propose. All you need is the proper MSD box, either the #6010 for the 24 tooth reluctor crank engines or the #6012 box for the later engines with the 58 tooth reluctor. Edelbrock also sells a box, which is actually made by MSD which will also work, but most people prefer the ones sold by MSD which allow you to use a laptop and change both the regular advance curve and also the vacuum advance curve. This lets you tailor it for various cams and etc. The boxes come with a harness that simply plugs into the various sensors and the coil packs. Plug it in and you are ready to go. I forgot to mention that ALL the boxes come with a set of small "pills" that you plug into the boxes. Each one has a different curve and they will get you started or could be " ideal " for your setup. As far as which reluctor (number of teeth) you have, it depends on the year of the engine, and from what I understand, even this is not set in stone. Usually, 2004 back are 24 tooth but there are exceptions to this, at least in GTO's and Corvette's. Not sure about the 5.3 truck motors. You can identify which reluctor by the color of the plug for the crank sensor just above the starter. Unfortunately, I have forgotten which is which, so someone else will have to come in here. I like your choice of the 200-4R. That is what I'm running behind my 6.0 with carb in my '34 coupe. You do know that you need a special bracket to fix the geometry of the carb linkage for the line pressure and kickdown to work properly?? This is critical on the 200-4R to keep from burning it up!! These are commonly available from Jeg's or Summit among others. Good luck and I'm sorry I was so long winded.
do you have the pn for the bracket needed for the 2004r...Imlooking in the jegs catalog now and I see something called a tv cable bracketfor 2004r is that the same part?
when doing a 6.0 with the msd carb kit is it best to change the cam?a guy told my i would need to change the cam from a fuel injected cam to a carburated cam .anyone knows any thing about this????i was told that it wont run right with the carb kit on a fuel injected cam...

650 Speed Demon runs great with stock LS1 cam in my install. The issue seems to be overlap, but the stock LS1 cam is not as agressive as many fuel injected cams I've seen... and although mine was a bit rich at start up, the timing curve with the MSD controller, and some de-tuning of the carb and it runs great. My Demon is mechanical secondaries due to the fact I use a Tremec 5 speed... love it when I kick the secondaries in.
Technically speaking, a carb that's optimized for FI will not be optimized for a carb, so it's best to change the cam out to something made for a carbed set up. As for using a 200 4R behind your 6.0, I too have this combo in my '66 Skylark. Previous to that I had a Buick 350 in front of this trans. I was able to keep the 750 Holley carb and accelerator/TV cable that I used on the Buick mill. The bracket that I used matched the TV cable's original application, an '87 Olds Cutlass with an Olds 307. I had to modify the bracket so that it would slip over the Holley spaced carb studs, but otherwise it worked just fine. My accelerator cable is a 70-72 Chevelle small block cable attaching to the cable pin furthest forward on the carb. The original accelerator pedal has been replaced by a '69-'72 Skylark pedal.

Hello all im goint to be doing a swap into a 63 impala this will be a strret car/ summer time driver with either a 200r or 700r eninge will be a 5.3.
My question is what would be a good carb to use for this application i was thinking a edelbrock 600 or 750 performer ,performer rpm intake and a 6010 msd
Any insite will be greatly appreciated thanks Anton

Reason: added to my post
Performer RPM intake with a Holley HP 650 vacuum secondary carb, 70 primaries, 74 secondaries or so, 30cc accelerator pump, #31 squirter and a yellow spring probably.
If i had to buy a carb I would buy one from Pro systems. They seem to get them PERFECT right out of the box. Within one jet chance. They drilll your metering blocks and all for the application. They are about $600 but they are the best carbs you can buy
I'm going to be doing a turbocharged blow-through LSx Swap into my '88 Monte Carlo in the near future to replace the current ProCharged SBC; and i'd like to do the front-drive distributor conversion based on the fact I HATE MSD and would NEVER have one of their computers running my engine (lets leave that alone for the moment though).
Is there an entire kit to make the conversion, or does anyone have a P/N list that could save me some time looking it all up? What do you use to drive the waterpump and alternator (only two accesories I will need)?
FAST makes a kit to run just like the MSD kit. It's a few hundred more though and does the same damn thing.
There is no list to copy and paste for you, you need to read the hundreds of threads and pick the parts you want based on your setup. It would be just as easy to run the setup EFI and much easier and reliable to tune since you are going turbo.
You mount the alternator in the stock f-body location, leave the tensioner at the top of the engine on the water pump and run a 53.5" belt i think it is to run both of them. There are a dozen or so threads on here with pictures of the setup.
Thanks Shawn, i've been finding little bits and pieces. I know it would be easier to do EFI, but I like my blow-through....i've been doing it for years making 600hp to the tires with no problems.
I am going to call FAST and look into their system, cause the distributor is looking to be ALOT more expensive and complex than I thought....it was supposed to be the cheap way.....
Well the MSD box i have personally used and works superb. I think the fact that just because you have a grudge with MSD you are to spend twice as much money for a setup that barely compares is silly. The MSD 6010s and 6012s work great for the LS1 platform and MSD is head of the carb swap really for the stand alone systems on Gen 3s.
Fast does have a similar system to the MSD 6010 but has probably only 1/10th as many users as the 6010. It costs more and then you also have to buy the harness. The MSD 6010 comes with the harness for $320 or so.
I've used the 6010 as well on a customer's car.....and it lasted about 30min before the box fried itself and wouldn't communicate. Just another drop in the bucket of msd failures i've run into. Again...not here to bash them though.
I actually called my old rep at FAST yesterday and they said they don't have a stand-alone controller for the LSx engines, but one is 6-8weeks away (which usually means they have no idea). Their XIM is only meant to be used in conjunction with their XFI setups. Do you have a part number for what you were talking about?
