7. Big-Inch Mill
Katech Performance now has a brand-new, all-aluminum race motor. The Desert Attack 500 starts with a high-strength billet, Dart 6061-T6 aluminum block (exclusive to Katech); adds in linerless, NiCom-coated, 4.205-inch bores; and finishes with an all-forged rotating assembly. The 8.2-liter V-8 displaces 500 cubic inches to crank out more than 700 hp and 700 lb-ft torque on race fuel (pump gas versions are also available but won't make 700 hp). Katech also supplies optimum header configurations with each race engine, as well as installation assistance.

9. Head Games
edelbrock's new RPM Xtreme cylinder heads for GM lT1/lT4 engines offer a mix of as-cast port design and custom CNC porting. Blending the affordability of as-cast ports with custom CNC porting in the critical areas (combustion chambers, intake entry, exhaust exit and intake/exhaust bowls) yields a powerful cylinder head at a lower cost than typical, fully CNC'd heads. All edelbrock intake manifolds and cylinder heads are cast and machined in edelbrock's own California facilities for absolute consistency and quality control.
