GM new LSX Block 480ci? Does anyone have any info on the new LSX block from GM?
I saw it advertised in the latest issue of GM High-Tech, has a part # of PN 19166454 and said it is capable of 480ci for $2,500.
What is the bore size?
How deep are the cylinder?
Is this an aluminum block?

No disrespect for SAM, but ERL deck deal isn't for everyone. I'd expect you would need to run custom headers for higher deck height. Custom intake manifold too.
I'd be more interested in GMPP LS1 block with large bore.

Full length headers are probably an issue on any of the tall deck blocks unless you run shorty's. I'm not sure if they are going to put it in their F body after testing the sheet metal intake or bump the compression and cam first. That will tell about headers. The intake has spacers (in SAM's posted pictues for LS7 heads) to run any LS intake.
