Cast iron LS blocks to 500+ cubes with LS7 heads...

454 blocks out now, bigger to follow.. heads out now...,
"One of the most important features of the Warhawk LS7X block is that it employs a priority main oiling system. Here, the crankshaft is lubricated first and the cylinder heads last—essentially the opposite of factory offerings. Because of this, you can use an economical wet sump oil system with 100% confidence.
You will find that the cylinder sleeves and surrounding aluminum block material is much thicker than in stock blocks. Even with a bore of 4.125” you’ll have .100” worth of dry sleeve and .300” support.
The most dramatic difference between the World Warhawk and factory LS1/LS7-C5R race blocks is the provision for two extra head studs per cylinder. This, of course, greatly increases the amount of available head gasket clamping force and more evenly distributes the load—providing the necessary sealing for high combustion pressure applications (superchargers, nitrous oxide, turbos). World’s new Warhawk LS7X cylinder heads also have provisions for the extra head studs/bolts.
On the bottom end, World has taken a cue from the GM C5R race block and utilized billet steel 4-bolt main caps, but has upped the ante through the use of ARP’s highly acclaimed 200,000 PSI main studs.
The Warhawk LS7X block is available in 9.240 and 9.800 deck heights. With this tall deck model, you can get an engine displacement approaching eight liters!
All standard GM internal components can be used in the Warhawk block. As a nice little extra, the block is equipped with both LS and SBC mounts, so it’s a bolt-in for any 1958-up Chevrolet.
Clearly, World’s Warhawk block represents the next level of technology for LS-series performance, and it’s available NOW!"
