In this episode we take a look at a chrysler 300 srt8 with a 392 6.4L hemi that is cammed as well as a dodge charger srt8 cammed 392 hemi 6.4L
Both the Chrysler 300 SRT8 and the Dodge Charger SRT8 equipped with cammed 392 6.4L HEMI engines are high-performance muscle cars that offer impressive power and torque. Let’s compare these two vehicles in various aspects:
Engine and Performance
Engine: Both vehicles have a 392 cubic inch (6.4L) HEMI V8 engine.
Cammed: A cammed engine means that the camshaft has been upgraded for better performance, typically leading to improved horsepower and torque, more aggressive sound, and potentially better throttle response.
Power Output
Stock Output: In their stock form, the 6.4L HEMI in both vehicles produces around 470 horsepower and 470 lb-ft of torque. With the addition of a performance camshaft, these figures can significantly increase depending on the specifications of the camshaft and accompanying modifications.
Performance Figures
0-60 MPH: The stock versions of these vehicles typically achieve 0-60 mph in around 4.3-4.5 seconds. With a cammed engine, this time can improve slightly.
Top Speed: Both vehicles have a top speed in the range of 175-180 mph, though actual top speed can vary based on tuning and modifications.
Both the Chrysler 300 SRT8 and the Dodge Charger SRT8 with cammed 392 6.4L HEMI engines are formidable vehicles that deliver thrilling performance. The choice between them often comes down to personal preference regarding design, comfort, and intended use. The 300 SRT8 offers a blend of luxury and performance, while the Charger SRT8 leans more towards a pure performance-focused experience.
Upgrading the camshaft in a 392 HEMI engine can significantly improve performance, increasing horsepower and torque. Here are some key points to consider when selecting an aftermarket camshaft for your 392 HEMI:
Objectives and Use Case
Purpose: Determine your primary goal. Are you looking for more horsepower, better torque, or improved fuel efficiency? This will influence the camshaft profile you choose.
