Why Choose a Crate Engine for Your Classic?

Modern crate engines deliver reliability, power, and parts availability that far outpace decades-old factory motors:

  • Reliability. Electronic fuel injection (EFI) and sealed cooling systems prevent vapor lock and overheating in Las Vegas’s summer heat.
  • Power & Efficiency. Gain 100–300 hp over stock, often with equal or better fuel economy.
  • Ease of Sourcing. OEM-backed crate engines come with full warranties and nationwide support networks.
  • Simplified Installation. Pre-assembled short-block and top-end configurations reduce shop time.
  • Future-Proofing. Ample aftermarket support means upgrades and rebuilds stay affordable.

Whether you’re restoring a 1967 Camaro, a ’70 Challenger, or a ’55 Chevy pickup, a well-matched crate engine can turn your project into a drivable, dependable daily—or a canyon-carving weekend warrior.


Top Crate Engine Options

GM LS3 (Gen IV) Crate Engine

Highlights:

  • Displacement: 6.2L V8
  • Power: 430 hp @ 5,900 rpm, 424 lb-ft @ 4,600 rpm
  • Weight: ~425 lb (complete)
  • Cost Range: \$8 000–\$9 500

Why It’s Great:
The LS3 is the “Swiss Army knife” of crate engines—compact, aluminum-block design with fuel injection. It fits in most A-bodies, F-bodies, Tri-Fives, and even some Mustang frames with minor modifications. EFI delivers crisp throttle response, critical during high-speed passes on U.S. 95.

GM ZZ6 Crate Engine

Highlights:

  • Displacement: 5.7L (350 ci) V8
  • Power: 405 hp @ 6,100 rpm, 406 lb-ft @ 4,500 rpm
  • Weight: ~415 lb
  • Cost Range: \$6 000–\$7 200

Why It’s Great:
A budget-friendlier LS option, the ZZ6 uses a cast-iron block with high-flow aluminum heads. It’s perfect for first-time swappers who want modern performance without the full LS3 price tag. Bolt-in swap kits are plentiful, and the cast-iron block tolerates Nevada’s altitudes without extra cooling mods.

Ford 5.0 Coyote Crate Engine

Highlights:

  • Displacement: 5.0L DOHC V8
  • Power: 460 hp @ 7,000 rpm, 420 lb-ft @ 4,600 rpm
  • Weight: ~515 lb
  • Cost Range: \$9 500–\$11 500

Why It’s Great:
The modern Coyote delivers high-revving excitement and direct-injection efficiency. Though wider than an LS, custom headers and narrow shock-tower spacers make it fit inside Mopars, Mustangs, and Customs. Electronic throttle-body and CAN-bus compatibility streamline integration with modern ECUs.

Chrysler 5.7L HEMI Crate Engine

Highlights:

  • Displacement: 5.7L V8
  • Power: 370 hp @ 5,150 rpm, 395 lb-ft @ 4,250 rpm
  • Weight: ~525 lb
  • Cost Range: \$8 500–\$10 000

Why It’s Great:
The HEMI’s hemispherical combustion chambers produce strong torque down low—ideal for heavy Mopars and trucks. Factory EFI harness and high-flow exhaust outlets simplify wiring and plumbing. Its steel block adds strength for high-boost turbos or superchargers in future resto-mods.

Small-Block Performance Packages

Highlights:

  • Displacement: 350–383 ci cast-iron
  • Power: 350–450 hp (depending on cam & heads)
  • Cost Range: \$5 000–\$7 500

Why It’s Great:
For purists who want “steel under the hood,” GM and Ford both offer fully-assembled iron small-block crate engines with upgraded rotating assemblies, heads, and mild EFI. They bolt into original mounts and retain classic engine bay aesthetics while providing improved reliability.

Factors to Consider in Las Vegas

  1. Heat Management. Triple-digit summers demand high-capacity radiators and dual electric fans—standard on all our swaps.
  2. Altitude Tuning. At ~2,000 ft elevation, engines run leaner. We dyno-tune EFI calibrations to optimize air/fuel and ignition timing.
  3. Emissions & Smog. Nevada requires smog for ’68-newer vehicles. We integrate catalytic converters and O₂ sensors seamlessly into crate harnesses.
  4. Cooling & Accessory Drives. A/C compresses air; power steering demands parasitic draw—choosing an engine with a compact accessory drive eases packaging.
  5. Weight & Balance. Aluminum-block options (LS3) shave 100+ lb off a cast-iron HEMI—improving handling on Summerlin’s winding hills.
