GM's new LSx iron block
 

I am attending the SEMA show this week and today I was making my way through the GM Performance Parts displays. I saw their new LSx iron block that comes in either a standard or a tall deck. Both blocks are capable to accomadate a 4.500 bore:eek: The standard deck can take up to a 4.50 stroke and the tall deck can handle a 4.250 bore! This means with the right combination of parts one can easily build a 500 inch LSx engine. The block is also made to accept ther new cylinder heads that has a extra head bolt per cylinder for those high boost applications. GM says it will easily handle 2500hp:eek:

hell yeah thats bad ass, i love how it says LSX on the front of the block, did you ask them to let you test it out? lol

:drool: Did you catch a price on that?

you can say that again. :) :hail:

that looks like a sweet block and i'm glad they forged in the extra bolt holes,it should withstand some pressure now.

would like to know a price too ill have to look into it..... let me make a call ill see if i can find out.

"the LSX block was engineered to handle up to 2,500 horsepower"

Damn i really like the color of that BLOCK :devil: :devil:

peace

i love it!

wow thats incredible. i guess this will be built to compete with the Warhawk?

One thing about the warhawk block. The GM guy said that they have only seen one block that was "built" it is on display here at SEMA. There are no running engines built on the Warhawk foundation. At least not to the guys knowledge or mine.

Theres a post about this in the LS2 section with detailed facts about this block.

ummmm......need to redo your post... ;)

Block: Precision cast iron, CNC machined
Bore: Siamesed, 4.25 max
Stroke: 4.500 max
Deck: 9.26 / 9.70
Main Cap: 6-bolt billet
Head Bolts: 6 per cyl. ( Accepts production 4-bolt)
Crank Sensor: Production 58X

seeing as how the LS series blocks all have a 4.4" bore spacing, that makes it just a "tad" IMPOSSIBLE to have a 4.5" bore ;)

i think i read in GMHTP that is was some where around 2500 for the blcok and they were using it in reggie jacksons camaro at SEMA
