086525 BMP Aluminum LS Block Chevy LS

The ultimate in replacement for Chevrolet LS1, LS7 or C5R blocks,World Productsí WARHAWK block is cast from 357-T6 aluminum, the absolute strongest available, and has importantimprovements that even factory race blocks donít have. This translates into engine builders being able to obtain morepower and enjoy improved reliability with WARHAWK-based engines.

Letís start at the bottom end. Main caps made of 1045 alloy steelbillet are employed. This material is tougher than the 1020 steel used by others. The caps are located by ring dowelsand secured with 200,000 psi tensile strength 7/16î ARP main studs and cross-bolts.

Itís important to note that the WARHAWK uses a priority mainoiling system, which feeds the crankshaft first and the top-end last. Others feed the top-end first and can starve themain bearings.

Water jackets are redesigned to provide more support around thecylinder ñ important for big boost applications. They also enhance cooling.

World Products also recognized that in order for engine builderswho employ power adders to maintain high combustion pressures with complete reliability it was essential to improve thesealing of the LS. With this in mind Worldís engineering team added provisions for the optional use of two extra headstuds per cylinder. They are designed to work in concert with the WARHAWK 12? LS7 cylinder heads, which also havethe extra bolt holes. Please note that the cast iron GM LSX block and the World Products WARHAWK block do nothave identical locations for the extra head bolts, however, standard 4-bolt GM LS heads will fit.

Another way that World has improved upon the quality of its LS blockis through the machining process (which is to QS9000 standards). All WARHAWK blocks are CNC machined in only twofixturing positions, which prevents the problems that can occur with production line blocks that are machined in multipleoperations and the tolerances stack from one machine to the next. Bottom line, Worldís WARHAWK is the most advanced,precision made block on the market for LS applications!

GET IT PREPPED!

For the enthusiast who is planning to assemble an engine in their home garage, getting the block in a RACE-PREPPED stateis a no-brainer. Our experienced staff performs important basic operations like:

ï Deck milling +/- .0025î
ï Main journal honing +/- .0004î
ï Cylinder bore plate honing .001î oversized +/- .0005î
ï Lifter bore honing +/- .0005î
ï Block hot tanking
ï Cam bearing installation
ï Freeze plug installation
ï Dowel pin and pipe plug installation
ï Block deburring
ïMachined surfaces sprayed with rust inhibitor
ï Protective wrapping

More and more professional engine builders are also recognizing the benefits of ordering race-prepped blocks insteadof endeavoring to perform these many tasks themselves. Many have realized that their time can be better spent doing criticalassembly work such as degreeing in camshafts and setting up the valve train. By employing race-prepped World blocks theshopís through-put can be accelerated, and there are demonstrated savings in terms of personnel, shop equipment, spaceand cash flow. Whether you're an enthusiast or engine builder,save time and money!

Please Note:
Warhawk blocks require the purchase of a mandatory block kit
