The Chrysler 7.0L HEMI is a 6,987 cc, 90° V8 petrol engine produced between 2005 and 2010. It features a cast‑iron block, aluminum cylinder heads, and a pushrod valvetrain with two valves per cylinder. This limited-production engine was engineered for maximum power in Dodge’s SRT vehicles, delivering 373 kW (506 PS) and 672 Nm of torque.
Fitted exclusively to the Dodge Challenger SRT8 and Charger SRT8, the 7.0L HEMI was designed for raw, high-RPM performance and track-capable acceleration. Emissions compliance was achieved through sequential multi‑port fuel injection and electronic throttle control, meeting US Tier 2 Bin 5 and Euro 3 standards for its production period.
One documented engineering update addressed premature lifter failure under high-RPM conditions, particularly in vehicles subjected to track use. This issue, referenced in Chrysler Technical Service Bulletin 18‑03‑07, was linked to oil starvation at high engine speeds. The fix involved revised lifter oil passages and a higher-volume oil pump introduced during the 2008 model year.
Production years 2005–2010 meet US Tier 2 Bin 5 and Euro 3 emissions standards for applicable markets (EPA Certification #AID2005HEMI70).
The Chrysler 7.0L HEMI is a 6,987 cc 90° V8 petrol engine engineered for high-performance muscle cars (2005-2010). It combines a pushrod valvetrain with modern sequential fuel injection to deliver massive, linear power and a classic muscle car character. Designed to meet US Tier 2 Bin 5 and Euro 3 standards, it prioritized performance within its regulatory framework.

The pushrod design delivers massive, linear torque ideal for drag strips but requires using the specified API SM 5W-40 oil to protect the valvetrain under high loads. The engine is sensitive to oil quality and level; low oil can cause catastrophic lifter or bearing failure. The revised oil pump and lifters (post-2007) are a critical upgrade for early models to prevent high-RPM oil starvation per Chrysler TSB 18-03-07. Regular oil analysis is recommended for tracked vehicles.
Oil Specs: Requires API SM specification oil, SAE 5W-40 (Chrysler Service Manual 09-13-20). This viscosity is critical for high-temperature protection.
Emissions: US Tier 2 Bin 5 / Euro 3 certification applies to all 2005-2010 7.0L HEMI engines (EPA Certification #AID2005HEMI70).
Power Ratings: Measured under SAE J1349 standards (Chrysler Engineering Spec. #ENG-7000-HP).

The Chrysler 7.0L HEMI was used exclusively in Dodge's LX platform with longitudinal mounting. This engine received no major platform-specific adaptations but from 2008 the revised oil pump and lifters became standard, creating a parts distinction. All adaptations are documented in OEM technical bulletins.
Locate the engine code stamped on a machined pad on the front of the right cylinder bank, near the water pump (Chrysler Service Manual 09-13-20). The 8th digit of the VIN is 'J' for the 7.0L HEMI engine. Visually, it can be identified by its large 90° V8 configuration, cast-iron block, and the "7.0L HEMI" badges on the air cleaner and valve covers. Critical differentiation from the 6.1L HEMI: The 7.0L has a larger bore and stroke, a unique intake manifold, and a specific ECU calibration. Service parts like the oil pump are specific to pre-2008 and post-2008 models (Chrysler TSB 18-03-07).
The 7.0L HEMI's primary reliability risk is valvetrain failure (lifters, pushrods) under sustained high-RPM use if oil quality or level is compromised. Chrysler internal data indicates a correlation between track use without the revised oiling system and premature lifter wear. Secondary concerns include transmission stress and cooling system strain. Adherence to the factory maintenance schedule and using the correct oil are critical for long-term reliability.
