1000 HP Capable — Pro Street 1000 Package

Four-Figure Capability. Blueprinted Precision. Built to Withstand Boost.

From $17,730

The Pro Street 1000 Package is a fully forged Barra long engine built for serious street, strip and roll-racing applications targeting reliable four-figure horsepower capability.

This package includes a forged 10-thou over bottom end with heavy-duty I-beam connecting rods, race-grade main and big-end bearings with 360° thrust support, upgraded piston pins, reinforced main stud hardware and billet girdle support. The block is fully machined, decked, bored and honed before precision assembly.

The oiling system is upgraded with a complete medium-pressure pump assembly, and the rotating assembly is measured, balanced and blueprinted to strict clearance specifications. The cylinder head receives a complete machine overhaul including valve servicing, decking and performance valve spring installation, paired with a high-performance camshaft package, upgraded timing system, reinforced MLS head gasket and premium head fastening system.

Every engine is assembled in-house with full clearance measurement, ring gap setting, thrust verification, oil clearance checks and a documented blueprint build report to ensure durability under sustained boost and high RPM use.

Four figure capability. Built for competition. Ready for boost.
