Description

A 1970 Chevelle SS in Fathom Blue with a 396 big block is already a strong combination — this one goes further with a freshly installed fuel injection system and a new Richmond Super T10 close-ratio 4-speed replacing whatever was there before. The 3-inch dual exhaust lets the big block breathe properly. Fathom Blue is one of the more striking colors from the 1970 Chevrolet palette, and on a hardtop body it looks exactly right.

The drivetrain work is recent and the car is described as running and driving well, with video available on request.

The Chevrolet Chevelle SS is the gold standard of the American muscle car era — a mid-size platform that took on every engine Chevrolet made, from the 396 to the legendary LS6 454, and produced some of the fastest, most purpose-built factory street machines ever sold.

Chevrolet Chevelle SS Buyer's Guide

Mike Sullivan here. The Chevelle SS needs no introduction, but it does need honest context: this is one of the most desirable muscle cars in the market, which means it's also one of the most heavily cloned. Understanding what you're buying — and paying for — requires more homework on a Chevelle SS than on almost any other classic. Get it right, and you've got one of the great American performance machines. Get it wrong, and you've paid a premium for a base Malibu with SS emblems bolted on.

The SS package ran from 1964 through 1972 on the A-body Chevelle platform. Each year produced something meaningful, but the 1969–1972 era is where the market concentrates. The LS6 454 of 1970 is widely considered the most powerful muscle car engine ever offered in a factory car, and a correct, documented LS6 Chevelle is the holy grail for serious collectors.

What to Check Before Buying

✓

Trim Tag Verification — Photograph and decode the trim tag — verify SS option code is present before paying any performance premium.

✓

Engine Casting Numbers — Record the engine block casting number and suffix code — verify against documented 396/454 casting references.

✓

Broadcast Sheet — Check under the carpet for the broadcast sheet — its presence and matching content confirms factory build.

✓

Cowl Rust — Inspect the cowl area at the base of the windshield — rust here is structural and expensive to repair correctly.

✓

Lower Quarter Panels — Probe lower rear quarters behind the wheels — probe with a pick, not just visual inspection.

✓

Trunk Floor — Check the trunk floor for rust perforation, especially around the spare tire well.

✓

Front Subframe — Inspect the perimeter front subframe for cracks at body mount points.

✓

Muncie Transmission (4-speed) — Test all gears — synchronizer wear causes rough shifts and is a $1,500–$2,500 rebuild.

✓

Hood Tachometer (if equipped) — Verify the hood tach is original and functioning — reproductions exist and an original adds value.

✓

Documentation Package — Request title history, any available service records, and original window sticker if available — all add value.

Common Issues

Clone cars misrepresented as factory SS models — documentation verification is essential. Cowl area rust (where the windshield meets the hood) is a structural repair on the A-body platform. Lower rear quarter panel rust behind the wheels. Trunk floor rust. Big-block 396/454 oil leaks from rear main seal. Muncie four-speed transmission gear synchronizer wear. Incorrect or incorrect-year engine and transmission combinations on restored cars.

What to Look For

The trim tag and broadcast sheet are the primary verification documents — decode these before paying any SS premium. Inspect the trim tag (located inside the driver's door or door jamb depending on year) for the SS option code. Verify engine code matches claimed displacement — 396 and 454 engine blocks have specific casting numbers that can be verified. Check the cowl area, trunk floor, and lower quarter panels for rust — these are the structural weak points on the unibody A-body. Verify the frame rails (front subframe perimeter frame) aren't cracked at the body mounts.

Price Guide

1964–1965 SS 283/327 cars: $20,000–$35,000. 1966–1967 SS 396 drivers: $28,000–$55,000. 1968–1969 SS 396 (documented): $35,000–$75,000. 1970 SS 454 LS5 (360hp, documented): $65,000–$110,000. 1970 SS 454 LS6 (450hp, documented): $150,000–$400,000+. 1971–1972 SS 454 (emissions-era): $35,000–$75,000. Base Malibus misrepresented as SS: $15,000–$40,000 — avoid without documentation.

Did You Know?

The 1970 Chevelle SS LS6 was officially the most powerful American production car of the muscle car era — 450 horsepower from the factory, with actual output estimated by most engineers at 490–510 horsepower. Chevrolet understated the rating to avoid insurance surcharges. The "SS 396" badge was kept on 1970 models even after the engine grew to 402ci — Chevrolet judged that "SS 396" had better marketing cachet than "SS 402." True 1970 SS cars have 396 badges on cars with 402ci engines.
