1967 Dodge Coronet R/T HEMI 528

A 1967 Dodge Coronet R/T already promised serious performance, but this owner decided the feared factory HEMI wasn’t enough. Samspace81 profiles an ultimate-street build packing a 528-cubic-inch Ray Barton HEMI making over 800 horsepower, all of it on pump gas. Backed by a bulletproof TorqueFlite and 3.55 gears, it pairs period-correct sheet metal with power built decades ahead of its time. See why this Coronet stops conversations at every show.

The badges on the fender say 1967 Dodge Coronet R/T, and to most eyes that already promises something serious. A factory R/T from that year was no gentle cruiser. But the owner of this particular Mopar looked at the most feared street engine of the golden era and decided it simply was not enough. What sits under this hood now makes the original factory HEMI look almost modest, and the number attached to it is the kind that stops conversations at a car show. This is not a restoration. It is an escalation, and the horsepower figure alone tells you someone was chasing the absolute edge of what a street car can be.

As samspace81 lays out, this ’67 Coronet R/T has been transformed into an ultimate-street monster built around a 528-cubic-inch Ray Barton HEMI, a name that carries enormous weight in Mopar performance circles. Ray Barton Racing Engines is legendary for building some of the strongest, most reliable HEMI powerplants anywhere, and this one is quoted at more than 800 horsepower. The truly remarkable part is that it makes that power on pump gas, not exotic race fuel, which means this beast is genuinely streetable rather than a trailer queen that only runs on race day.

Backing the massive engine is a TorqueFlite automatic, one of the toughest transmissions Chrysler ever produced, paired with 3.55 gears and a supporting package of upgrades engineered to actually put all that output to the ground. The Coronet R/T was the right starting point for this kind of build. As Dodge’s performance flagship for the model year, the R/T came with heavy-duty underpinnings and the attitude to match, making it an ideal foundation for a modern high-horsepower reimagining.

What gives this car its appeal is the blend of vintage sheet metal with genuinely modern power. From the outside it reads as a period-correct classic. Turn the key and it behaves like something built decades ahead of its time. That combination of old-school looks and 800-plus horsepower has become one of the most desirable formulas in the hobby, and this Coronet executes it with real credibility rather than empty bravado.

Samspace81 has built a following on exactly this kind of high-quality classic and muscle car content, and this Coronet is a standout example. It is a purpose-built street brawler that honors its Mopar roots while completely rewriting the performance envelope. Few cars manage to be both this authentic and this outrageous at once.
