Dodge Viper SRT-10 8.4L V10 Crate Engine

A Dodge Viper SRT-10 8.4-liter V10 crate engine, the fourth-generation ZB II version of the Viper V10, pulled from the Dodge Performance Division lineup for a Viper restoration, swap, or high-displacement custom build.

What this engine is

Based on Chrysler's LA family of 90-degree V-configured engines, this naturally aspirated V10 uses an aluminum block and cylinder heads with variable valve timing and multi-point fuel injection, with the factory rating running past 600 horsepower and past 560 lb-ft on the torque side. The intake manifold is finished in silver with dual throttle bodies and ten individual runners, and each valve cover is finished in red and carries the Viper logo, with a Mobil 1 logo on the oil cap.

What to check before buying

Shipping weight runs around 650 lbs, so plan freight and engine hoist capacity accordingly, and verify your chassis and mounts can accommodate a 90-degree V10 rather than a V8-pattern engine bay before committing to a swap. The assembly tag on this unit shows part number 5038516AA with a 2010 date, which is worth noting for anyone matching casting details against a build sheet.
