Robin L,

So then you are saying this is an LSx based engine and not the new LSt big block?

So this engine block has the same exterior dimensions as a standard LS1/LS2/LS6/LS7 etc.. block but in Iron?

Thank you in advance for the clarification.

 

Yes it is a small block LS series configuration.

It has extra head bolt holes, revised oiling, thicker webs and more material in the cylinder walls.

I should have a formal list of features in a week or so. I will post them as soon as I see them.

Robin

 

Thank you.

Was that other post correct when it stated that the same block will be available in aluminum as well before long?

 

sounds like the warhawk block that is soon to be released

 

LSt big block?

 

Sounds like the future should be interesting.

 

you know something... spill the beans!

 

 

Something still doesnt sound right. I dont believe the bore could be that big. Have you seen pictures of the LS7 block and how little material there is between the bores? I dont think you could go much bigger than that with the block being longer and wider.

 

i assume its going to be an iron block
similiar to a bowtie block, maybe this will be the LS bowtie block

 

STILL Iron or not I dont believe it. There just isnt enough room for it. Unless some mystical engine wizard made it, I cant believe it.

 

You guys might be on to something there.

 

[master of obvious]
you know, when you put it together like that, it sounds like World is making a block for GM.... :lmao:

here's a few cropped pics

 

It is iron, and I have seen pictures of an un machined casting. You are correct to assume that the bore is limited due to the LS series bore spacing. There is only so much material between the cylinders. There is however enough to build a 500 inch LSX engine. The more cylinder pressure the more you will want to be consevitive on the bore size.
This is a killer LS series block. It's not intended to be a one off with different bore spacing.

A higher deck versin will follow for those who want a bunch of stroke and a long rod.

World is not making the block for GMPP.

Power adders should be careful about bore size. An NA engine will get away with close to 4.250 I would think. Again when we see them we will know a lot more.

Please don't quote me on the 4.250. It may require offsetting the bores.

More as I hear.

Oh BTW. The carb intake for the LS7 heads is now available. I'll post the part number after I verify it.

Any idea how much more the aluminum version will be when it hits?

Or what will be different about it?

 

one question, who are u Robin L?

 

At this point GMPP is focused on the Iron LSX block. The aluminum ..IF it happens will be at least a year away.

The market has other people developing aluminum blocks.

The raised deck version of the iron block should be out 3 months after the standard version.
