Mains: 2 piece rear main seal with billet steel splayed caps 350 or 400 main.
Wide pan rail.

I keep hearing bits and pieces about it too but I don’t have Facebook either. There a copy of a post on ltxtech though. I wish there would be an announcement on one of the forums about it. I really hope it works out.
this idea has at made at least one round years ago. There was a lot of enthusiasm, but it dwindled quickly. Right now there’s no way anyone is going to spend that kind of money UFN.
And supposedly the company that is casting this LTX block will give the option for it to be aluminum. So if it costs me $4000 next year so be it.
How many was “us?” I thought it was scrapped because there wasn’t enough interest. i was highly interested willing to spend the money, but i don’t feel as though i was fucked over.
doesn’t this other company still need tens of thousands of dollars from buyers before they’ll even produce one of these blocks?

Maybe someone can convince the Australians to produce a billet aluminum LT1 block. They'll probably only need to sell a dozen or so to see a return on the investment.

Meanwhile they offer a custom aluminum billet block and iron block choices. Makes no sense.

Dart didn't want to invest in the tooling which they claimed would have set them back $70,000. Which I really don't get since the LT1 is pretty much a SBC with a few differences.

I totally Agree and if the funds were there for me I’d definitely go with the aluminum block, My build isn’t an overnight build because I just simply can’t afford it to be but I’m willing to take every bit if weight savings that I can Off of my car! And as crazy as it sounds I wouldn’t mind building a stock stroke big bore that i can really twist hard with a solid roller but that would be something I'd be willing to discuss with Karl Ellwein because I think he's really who I'd like to have build my engine.

Doesn't this new outfit also want ~$50K or more to retool their machinery to produce this block?
I'll be honest I don't see a lot of people buying into a big bore lt1. At 4k a block im not gonna at this time if avaliable. I have other places I spend that money first. A 4k block is for someone pushing the limits of the lt1 block.

project is nearing completion….before all of the covid stuff went nuts we were preparing to open up for preorders....Facebook is where the majority of the information has been released. As things get finalized instead of just "getting close" one of us will find time to hit up the forums...very few folks are forum only at this time
I say we stay positive about this one, an aluminum big bore LTX block would be awesome! Not everyone wants to swap to an LSX. I love the engines, I think they're great and I have a few laying around and I can't say that a 6.0 swap into my car hasn't crossed my mind at times but I really don't want to, I want to keep it LTX based and I'd love the weight savings of aluminum and the big bore possibility.
