Production is scheduled to start in Jan 2013. This one is going to have direct injection into the cylinder.

Very cool. But will probably be less swap friendly due to the 90 degree block.

I'm not following, the current engines are 90 degree V-blocks as well, so swapping shouldn't be any more difficult, not counting the Direct Injection stuff.

Doh, you are right.

physically, it looks like it's the same size as the current LS engines, so swapping shouldn't be an issue once people get used to the direct injection stuff. an efi swap into an older car is practically a plug in deal these days, and i predict that someone will come out with an easy way to swap these motors into an older car within a year- maybe GM will offer a package like they do with the current turn key LS3 emissions legal crate motors..

This new LT1 uses a mechanical fuel pump to handle the DI correct? I would imagine all that needs to be done in swap application is to feed the mechanical pump with a conventional electric pump. That mechanical fuel pump also mounts in the rear of the engine much like a dizzy and is cam driven. I can see carb'd and dizzy conversions for the things in the future. Pretty cool engine.

It looks like the cam has a three sided lobe in the rear to drive a pushrod that in turn runs the pump. I don't see an easy way to make a distributor work, nor any need. Also, why on earth would anyone swap a carb on an engine that uses the latest direct injection technology...

People carb LS engines all the time. I've seen a carb'd 5.4 modular with a distributor running off the driver's side cam gear. Looks real cool.

I'm sure it's done for the cool factor or some similar nonsense. Good point on the fuel pump. Maybe we wont be seeing distributor conversion in the future.

GM came out with a front cover for the LS engine family that uses a 5.0 Ford distributor driven off a gear that bolts to the front of the camshaft about 10 years ago. it makes the LS engine family look a lot like a Ford Windsor engine if you don't look too closely... i predict that they won't do that for this engine..

I looked at the engine pretty thoroughly at SEMA. It looks a lot like the LS engine. It appears that the motor mount bosses on the side of the block are the same. It also looks like the exhaust manifold bolt pattern is the same. Water pump looks funky with the pulley off to the side.

I had no idea. I imagine that would look very Windsor-ish. A front distributor on an LS or this new contraption would be silly. I think my original claim of mech pump deletion kit allowing for a rear mounted distributor being a future add on still holds water for whatever that is worth to the topic.

Engine selection and presentation can be as much an "art" as the paint, wheels ect on a build. To quite a few, an engine is not always an icky metal appliance that makes the car go. For the record I do not imply that you think one way or the other.

I can see a desire for REAR distributor conversions for these engines for reasons of engine presentation and appearance.

As I understand it, this is not the Gen V engine, but merely the latest and final iteration of the Gen IV.

GM just keeps stepping up to the plate. Bravo. Now please make us a kit with a nice copy of the Holley tunnel ram, these heads, and a fuel pump(belt driven?) as a retrofit for around $1500 including small parts such as injectors and pre-fit fuel lines. I'll be waiting for the USPS man. Thank you.
