Dodge and Ram offered two unique V10 engines — one built for heavy-duty trucks (8.0 Magnum V10) and one for performance cars (8.3L / 8.4L Viper V10).
• The 8.0L Magnum V10 was available in Ram 2500 & 3500 (1994–2003), delivering massive torque for towing.
• The 8.3L & 8.4L Viper V10 powered the Dodge Viper (1992–2017) and the Ram SRT-10 pickup, producing up to 645 hp.
Both engines are iconic, but they have their own sets of common issues.
