With its powerful 426 HEMI V8, aggressive styling, and NASCAR influence, the 1970 Charger R/T HEMI remains a highly sought-after collectorโ€™s car. Whether you’re looking to invest in an original numbers-matching example or restore a project car, itโ€™s crucial to inspect key areas to ensure authenticity, condition, and value.

This 1970 Dodge Charger R/T 426 HEMI Muscle Car Buying Guide provides a detailed breakdown of what to check during an inspection, helping you avoid costly mistakes and potential fakes.


1. Verify the Authenticity of the 1970 Dodge Charger R/T 426 HEMI

Due to the high value and rarity of the 1970 Dodge Charger R/T , many standard Chargers have been cloned to look like authentic HEMI cars. Before purchasing, verify these key identification points:

A. Check the VIN (Vehicle Identification Number)

1970 Dodge Charger R/T 440 VIN Tag

The 1970 Dodge Charger R/T should have a VIN that starts with XS29:

  • “X” โ€“ Indicates the Charger R/T package.
  • “S” โ€“ Represents the Specialty model (R/T performance package).
  • “29” โ€“ Indicates a two-door hardtop.

๐Ÿšจ If the VIN does not start with “XS29”, it is not an original Charger R/T!

B. Confirm the 426 HEMI Engine Code

The 1970 Dodge Charger R/T HEMI came with the legendary 426 HEMI V8, but not all R/T models had this engine. Check the 5th digit of the VIN:

  • “R” = 426 HEMI V8 (original factory HEMI car).
  • “U” = 440 Magnum V8 (not a HEMI).
  • “V” = 440 Six-Pack V8 (not a HEMI).

๐Ÿ”ฅ Only a VIN with an “R” in the 5th digit confirms a factory-original HEMI Charger R/T!

C. Fender Tag & Broadcast Sheet Verification

  • The Fender Tag (located on the driver’s side inner fender) should include:
    • “E74” = 426 HEMI Engine Code
    • “D32” = Heavy-Duty Automatic Transmission (if equipped)
    • “D21” = 4-Speed Manual Transmission
  • The Broadcast Sheet (often found under the seat or inside the rear seat) further verifies the carโ€™s originality.

2. Inspect the Body for Rust & Structural Issues

The 1970 Dodge Charger R/T 426 HEMI is over 50 years old, making rust and hidden repairs a major concern. Hereโ€™s where to check:

A. Common Rust Areas on a 1970 Dodge Charger R/T

  • Trunk Floor & Rear Frame Rails โ€“ Water accumulation causes rust.
  • Lower Quarters & Rocker Panels โ€“ Inspect for signs of patch panels or rust repair.
  • Roof (Vinyl Top Cars) โ€“ Moisture under the vinyl top can cause hidden rust.
  • Firewall & Inner Fenders โ€“ Rust in these areas can weaken structural integrity.

๐Ÿšจ Use a magnet or digital paint meter to check for excessive bondo or hidden rust repairs.

B. Check for Signs of Previous Accidents

  • Frame Straightness โ€“ Look for misalignment in door gaps and panel fitment.
  • Underbody Welds โ€“ Uneven welds may indicate prior crash repairs.
  • Bumper Alignment โ€“ Poorly aligned bumpers can suggest structural damage.

3. Mechanical Inspection: Engine, Transmission, and Rear Axle

A. 426 HEMI Engine Inspection

  • Look for the correct block casting number: 2468330-1 (located on the passenger side of the block).
  • The engine pad should have a matching partial VIN (confirming it’s original to the car).
  • Check for proper carburetors โ€“ The 426 HEMI used dual Carter AFB 4-barrel carburetors.
  • Listen for ticking sounds โ€“ The Hemi’s solid lifters are naturally noisy, but excessive noise may indicate wear.

B. Transmission & Drivetrain Verification

  • 4-Speed Manual (A833) โ€“ Verify the Hemi-specific “Hemi Box” transmission.
  • 727 Torqueflite Automatic โ€“ If equipped, ensure it has the HD torque converter.
  • Dana 60 Rear Axle โ€“ HEMI Chargers came with a 3.54:1 or 4.10:1 rear gear ratio.

4. 1970 Dodge Charger R/T Interior Inspection

The interior of a 1970 Dodge Charger R/T plays a significant role in value. Hereโ€™s what to check:

A. Factory-Correct Interior Features

  • Rallye Gauges with Tic-Toc-Tach โ€“ These should include a factory tachometer and clock.
  • Woodgrain Center Console (Optional) โ€“ Manual cars should have a pistol-grip Hurst shifter.
  • Door Panels & Seat Covers โ€“ Look for correct patterns and factory colors.

B. Verify the VIN Tag & Dash Pad

  • The VIN should be riveted to the driver-side dash.
  • Check for factory door stickers and tags for originality.

๐Ÿšจ A missing or tampered VIN tag is a red flag!
