The LS motors get better mileage I would say.... better technology.

sbc is 1950's tech. LS series is Today!

What kind of gas MPG do you get ,and on the 400 do you get O-Drive right .
I want do the EFI but his sound about right...

A TH400 does not have over drive... Only the 200r4, 700r4, 4l60, 4l60e, 4l65e, 4l80e etc.

I estimate i am getting around 20mpg. No odometer to confirm this though.

Has anyone used the XDi with the LS2? Does the XDi use the factory style plug on the crank trigger wheel, allowing use of the factory reluctor wheel since they are both 60-2?

I'm thinking of going with a carbed LS setup on my Chevelle, great thread guys!

For those that have already done this, any advice on what I should look at buying, longblock wise?

Look for something to handle some nitrous cause plate kits are cheap and make some power.

Thats a sweet distributor setup. How does it perform? ever with nitrous? I was thinking about going that way with my boat motor. I ended up using the edelbrock/msd conversion. I feel too confined with this setup. After reading all this I think I am going to get the msd 6010 box. I wanna put the squizzzzzzzzz on some foooozzzzzzzzzz.

Forgot, how do you set the timing on the dist setup?

Hey shawn. With that catch can and my ls6 valley cover. Would I just cap both valve covers and be ok with that, or would I still need a breather on the covers? Im puking alot of oil on my top end. Im running 20-30 minutes wide open sometimes on a good river run.

I have an ATI kit that you use to drill the crank and put a dowel pin in it. This locates the balancer so timing can be set. The only hard part about it is finding true TDC with the heads on in the car, like I did. Here is a pic of mine from last year. I am putting a Dominator on it this year. There are some other pics of the set up on my site www.loughengines.com.

To *93ls7z* or anyone else that needs to know. You can easily find TDC on any engine by using a positive stop. Both Jeg's and Summit sell a tool (cheap) or you can make one yourself out of an old spark plug by knocking the insulator out and threading the inside for a bolt to adjust thelength you screw into the cylinder. take all the plugs out, screw the tool in # 1 like a normal plug, turn engine over by hand (slowly) until piston comes up against tool. make a pointer out of stiff wire and fix it to engine witha bolt and bend end to a spot at 90* angle to crank pulley (close to pulley and pointing at center of crank). Mark crank pulley at that spot. Turn crank by hand (slowly) in OPPOSITE direction until piston comes up against tool again. Mark spot at your pointer again. Halfway between the two marks is exactly TDC. The adjustable bolt lets you adjust your tool so the piston stops about, say 15-20degrees either side of top dead center. Once you check it a couple times, you can make a decent mark on the crank pulley. Bear in mind, unless you pin or key the pulley, it will change every time you remove the pulley. After you do it a couple times, it's very simple. Hope this helps someone. Ron

Hmm I'm not sure about the LS6 valley cover. Hows it work? It draws vacuum from the top of the LS6 valey cover rather than from the valve cover? You would need to connect a vacuum source to that port with pcv valve, then a breather on one or both of the valve covers. I'm really not sure. It's been a while since i read up on them.

Its got alot of vacuum. I was looking at the norris web site and they had some pics up. They had the intake and ls6 valley cover hooked up to the can. I was wondering what they may have done with the valve covers(it didnt show.)

Anyone ran nitrous with the distributor setup yet?

Heres some PCV bookmarks i saved when i was reasearching my setup.

Yes. Works just like the older engines with a distributor as far as timing is concerned.

Didn't say I couldn't find it, said it wasn't easy. I had the cover, oil pump and timing set off the engine when I decided to do this swap so at the time there was no crank pulley to reference off of. I used the snout of the crankshaft to mark for TDC then drill accordingly for the dowel. But thanks for the quick lesson for those that didnt know.

Thanks shawn. Both of those really helped alot. I have mine set up all wrong.
