Finally a cheap alternative for an all aluminum engine! I was looking through the new CHP and about 2 or 3 pages in to it I saw the add for the new carbed ls1 intake. I looked up the part number on summits website and all it said in the product discription was "intake manafold" but it carried a $700 price tag. Any way the kit is built off of a performer rpm intake. The kit includes an intake, MSD built 6al type box, and ignition wiring for the factory coil packs. Not bad considering a pro billet, 6al, and a good intake will set you back 6 bills or more. It almost sounds too easy. without the fuel injection you wouldent need the ecm or any of that right? so would you need any of the factory wiring other then the coil packs? Sounds cool.

The fun begins! You'd still need wiring for the ignition though.

I wish somebody would come out with a composite manifold. If they can solve the fuel resistance problem, think of the heat transfer and weight savings!

the intake come with all the wiring you'd need to use the fatory coil setup. i saw the intake this summer at the Car Craft Summer Nats, and it is a pretty tall single plane.
i still can't, for the life of me, figure out why anyone would want to ditch the efi and go with a carb, tho.

i would do it just for for the aluminum block.

I think it was Hot Rod that tested it and the carb'd setup actually made a few more HP up top with a 650 Speed demon carb than the EFI.

Granted driveability would suffer, but you could get a bit more wild with the cam if you have a carb sitting on top. You could get away from the super-wide LSA cams that are needed with the computer . . .

I like the idea personally -- a big solid roller cam, a set of CNC ported the small chamber 5.3L heads on a 6.0L shortblock, and you have yourself a real screamer. Them factory castings are flowing well past 300 cfm with a simple CNC port job and thats using factory valve train hardware.

This could very well be the future power plant of our cars when the old small blocks are all used up.

PS. and these LS1 based engines have been stroked and re-sleeved to make in excess of 427"

Eric,

You don't honestly think they will ever be enough of them in the Boneyar--, er -- Recycling Ceenter to be "CHEAP" like the old motors, now do you???

Being aluminum, I figure they will end up melted down with "UBC's" and made into "Barley-pop" cans b/c of their aluminum scrap value when they are shot!!!

PDQ -- good point, there probably won't be enough of them in the boneyards (or at least as many as the old SBC) for quite a while, but they will certainly be available in the crate . . . and don't forget that the trucks are using the 5.3L and 6.0L even though the Camaro is pretty much dead.

It's kind of sad that the good 350 and 400 cores are starting to get scarce . . . we might not have a choice but to go with the new aluminum in another 10 years. And I DO think they are worth a bunch more as cores than as "Barley pop" cans LOL smile.gif

Isn't the 6.0 an iron block? I think I saw a complete rebuilt short block for $3K somewhere. Not too much different than some overpriced 383 short blocks. I'd like to build a carbed LS1, but not till the overall price evens out a little more.

I just received my new car craft and they have a big spread on the LS1 engines. 580 hp out of a stroked 6.0L. Not bad.

Yes, most 6.0L are cast iron, unless you get one out of an Escalade. In Jeff Smith's editorial, he interviewed the GMPP manager and he said that they have produced over 1 million LS1 type engines in a year, so I think the prices will drop. You can get a bare 6.0L block for $700 from GMPP. While not a $100 350 block from a junkyard, it is definitely cheaper than I thought. What is going to kill you is the all the little stuff (accessories/exhaust) and electronic stuff you will have to acquire. SLP sells a stroked 6.0L short block for $3500. Pricey, yes, but you get forged everything so...I just figure everything is at BBC prices as compared to a SBC. A company called Patriot makes LS6 style heads for $1600, which is about the price of BBC aluminum heads.

So while things are on the expensive side now, I think prices will fall. Especially when people realize that a truck intake will produce just about as much power as an LS6 intake(like w/in 5 hp), although they are pretty tall and ugly.

I like the idea of a carb on an LS1 engine, I think it is a great way to reduce cost, although there will be trade offs. If you are used to running a carb though I don't see where you are losing out unless the carb gives up serious HP and torque to the EFI.

Something to think about.

What about auto trans. Will a turbo 350 or 200R4 bolt up or are limited in type of trans you can use?

Never mind just looked at link above.

But check this out !!

Escalade Crate Engine for a good price complete long block (http://www.sdpc2000.com/catalog/120/products/229029/6_0L-Gen-III-Escalade-Crate-Engine.htm)

My BIGGEST issue with the LS1 is... and I'm a little embarrassed to say this:

it's UGLY. LOL. I mean, I just don't like the look of it at all. Doesnt look clean to me, the intake, for instance... I know this is personal, and I know as I keep looking at them in every dam magazine coming out now, I will get used to them... but...
ugh.

I like the look of the coil packs on top of the valve cover. I agree that they are still alot of money. seems like 4500 is the going rate for a t56/camaro engine combo. If I would have known that I could have saved a bundle. I spent so much money converting my car to a 4 speed and then even more building my engine. Id have to say that I easilly spent close to 5 grand on the engine and I already had the block, rods, and crank. Its funny how times change. I remember when I was pressed for an LT1 take out a few years back :rolleyes: Im glad I didnt. before I built my muncie a t56 was a major job as the th400 crossmember was the only source for installation. oh well time moves on.

pdq67 Actually, you can sometimes find these motors even cheaper then the "old motors."

Those LS1 guys are always swapping out engines for the 6.0 Iron blocks, or C5R blocks, or crate LS1's. And when these guys have extra parts laying around, they dang near give the stuff away, graemlins/thumbsup.gif .

I recently bought a complete LS1 shortblock for $400, with less then 30k miles on it. I also bought some good complete set of heads with SLP rockers for $250, also less then 30k miles, the rockers alone cost that much. You can't even get a decent set of iron heads for the gen1 for that price. You can also find accesories cheap to, things like timing change cover, lifter valley cover, intakes, lifters, cams, etc. for cheap.

Maybe I can put this thing together, carb to pan for less then $2,000, :D . I'd be hard to put an iron block 350 together for that.

I think this is pretty cool. This gives some of the people who may have a smaller budget, but want the benefits of an alluminum block, and all the excellence of the LS1.

Yes, I wonder about the transmissions you can use with the LS1 too, since I just bought TKO 5 spd....When I bought it, I was thinking a 383, but now...I don't know.

You still get a very good flowing head, with very good combustion chambers, better valve angles, and the revised firing order.

You also still get the very stout bottom end. :D

What about motor mounts and headers. I know some companies make them, but aren't they expensive??
