Just like to add that the LSM block comes with billet 4340 main caps. The aluminum billet block is available with either sleeves or plated with Nikasil for the same price. Block will accomodate large bearing cam up to 60mm roller. The block is also available in either billet aluminum or billet steel.

Good thread here.......
There's a company called ERL that makes what they call a Super Deck block. They claim they can handle a 4.200" bore.
For more info you can go to www.erlperformance.com or call (812)948-8484
The future of the Gen 3 performance industry looks bright

Updated. I can add the ERL, but since it is re-sleeving a stock block, I have left it off for the moment. This was primarily looking at aftermarket blocks.
