A Naturally Aspirated 426 HEMI Magnum
Rather than relying on a supercharger or turbocharger, this Dodge Magnum produces its power through a naturally aspirated 426 stroker HEMI.
The owner explains the current engine and drivetrain combination, including the change from 3.09 to 3.91 rear gears. The Magnum is still running its stock transmission and stock torque converter, leaving additional room for the car to improve.
Current Build Highlights
• Dodge Magnum SRT8
• Naturally aspirated 426 stroker HEMI
• Stock transmission
• Stock torque converter
• 3.91 rear gears
• Street-driven Mopar wagon
• Best pass of 12.15 at 113.70 MPH
A future higher-stall torque converter could help the Magnum leave harder and take better advantage of the stroker engine’s power.
12.15 at 113.70 MPH
The video includes multiple quarter-mile passes at Toronto Motorsports Park in Cayuga, Ontario.
The Magnum saves its quickest run for the final race, recording a 12.15-second pass at 113.70 MPH.
That is solid naturally aspirated performance for a large, street-driven wagon—especially with the stock transmission and converter still in place.
