with a little research, you'll realize that GM re-uses quite a few engine designations. the reason I mentioned the dual belt pulley is that GM seems to have been crossing over to electric power steering on many vehicles, and in the pictures, you can see the alternator, a/c comp and w/p already, one belt to run just a P/s pump seems a little silly to me. I think it is for some kind of supercharger setup myself.

 

Tushay !
Forgot most things are going electrical nowadays
I think your right tho
Gm probably also used it to save money also to run same harmonic balancer across there truck and car Gen V Engines it might be a supercharger setup up but at the same time it might of been designed for it to be used in different ways depending what pulley setup is being used and what platform engine is in

Should be interesting on the numbers the supercharger would put out

 

I've seen a lots of videos about the new Corvette engine and I'm impress. So much that I'm thinking if it will be possible to put that engine on a Third Gen. What you think about this?

 

I don't think gm is selling the crate engine from the new vettes yet... Prolly can get away with 2012 6.2 v8 that they put in them now...but their expensive, I've seen the ls3 from the new camaros on eBay go for over 10 grand....wouldn't be surprised if the ls3 from the vettes go for more

 

you can buy a turn key erod LS3 for 6500 from GM

just wait for the first idiot to wreck a vette

 

I Agree someone will crash and end up in a salvage Yard and wee can buy it. It wont be cheep but it is direct injection and has cylinder deactivation something nice to have in a third Gen.

 

Well the first wrecked 2014 vette has already surfaced and its not out to the public yet.Awesome lol.

 

Hmmm people converted 2nd Gen LT1 Heads to fit 1st Gen SBC wondering who will try to see if Gen III LS with NEW LT1 Heads will mate together ?????

hmmm might not need to buy whole engine...

bolt patterns look the same minus two head bolts on intake side just a theory now !!!

guess time will tell when see a actual full comparison of both blocks etc

 

new vette wreck how much they will sell the engine

 

And more importantly to those of us not daily-driving 450 HP through commuter traffic: They're doing a 4.3L V6 version totally different from the 4.3 we've had for decades now. Expect 300 HP in the C1500, and 30 MPG if swapped into a car. Cam, long-tubes, less-back-pressure-mufflers and tuning should get 350 HP with 30 MPG. I'm surprised, except for the CAFE standards. We all expected the Camaro's 3.6L to replace the 4.3 and the 4.8, because that's what F150 and Ram 1500 did, but I think the GM 3.6 will die soon, since Europe has a 2.8L turbo version of the 3.6L with more output and more MPG. Biggest problem I see is the need for a MegaSquirt since GM won't be offering the 4.3 with a true manual transmission. But it will make for the smallest and lightest 350-net-HP reliable engine yet. compression is at least 10.5:1, or was it 11.5? Anyway, that means no boost. Besides, 350 HP should max out the stock fuel delivery. I'd expect it to survive a wet 100-shot nitrous kit. A 450-HP all-aluminum 4.3 anybody should be able to copy. Sweet! At least the 'vette 450-HP version will guarantee the existence of adequate fuel flow components to hop up the truck 5.3L version.

 

Update: GM showed off the LT1 crate engine swapped into a 71 Corvette for Jimmy Johnson.
All our LS swaps are now obsolete.

 

Just because someone else has more money than you doesn't by itself destroy all the merit of whatever can be accomplished with older tech. Nothing PG-rated feels better than destroying a shiny new supercar with a ratty old ponycar hiding a ULEV engine and capable of more MPG than that supercar, while costing a tenth as much, and having twice s many seats. There's good reason we call it "more money than brains".

 

The other thing is, you can say YOU did it. These rich dudes always say "we" (usually refering to them telling the shop what to do)or "they" did it. Most of them will never say "look what I did". It doesn't matter what the swap is, but there is a huge gap in the respect-o-meter from people who actually do the hard work, research, etc, to people who pay someone else to do it.

So no, LS swaps are not obsolete. Not the "latest and greatest" but not obsolete.

 

I am about to do a 5.3 LS on mine, as far as I am concerned it is new to me, and with any luck will be better than my 350 was since it was swapped from a 305.

 

I don't think "obsolete" fits. To me, it's great someone who can do anything is on board for a version of what we are doing.
Plus, when was the last time you thought a '71 Vette was desirable?? JJ's is.

 

5.3 will be very nice!

 

One thing i did notice about the new LT1 as a swap, since I've been holding off on an LS3, Is the lack of power steering pump in the acc. drive, GMPP as far as I know, is not planning on making a pump, so an electric pump will have to be installed, such as the MR2 Toyota Unit. As far as fueling, all the documents from GMPP lead to the thought that a similar setup for an LS3 would suffice. It's actually not all that much harder of a swap if you can afford the crate and the control pack, plus having a little skill would help. I'd love to do it, but sadly the LT1 is a bit too much more expensive than the LS3 for me...

 

Yea the 5.3 has been very nice. I am curious about the LT1. Maybe some day one of us will do the swap successfully ... or maybe get thje electronics from the new LT1 to work with the LS1 style blocks --- sorta like the sbc with the 0411 pcm

 

This thread is useless and doesn't deserve to be a sticky.

 

I wish I could get the time back that I wasted reading it.
