Hemi History

Chrysler introduced their first Hemi engine in 1951, a 241 cubic-inch V-8, later enlarged to 331-cid. They copyrighted the name "Hemi" and used it extensively in advertising campaigns.


The hemispherical combustion chamber design has been around since the beginning of internal combustion engines. Jaguar's XK-120 Roadster featured hemi-shaped chambers in 1948. The DOHC straight six-cylinder engine would go on to power their XKE models through the Sixties and Seventies.


426 Hemi In Racing

Chrysler's fabled 426 Hemi engine debuted at the 1964 Daytona 500. Richard Petty would lap the entire field before driving his #43 Plymouth to the winners circle. Hemi-powered stock cars finished first in 26 of the 62 NASCAR Grand National races this year, and would help Petty win his first of seven NASCAR championships.


In January of 1965, NASCAR rules banned limited production engines like Chrysler's Hemi. The rule change was not meant to punish Chrysler, but rather to allow other manufacturers to be competitive. In retaliation, Chrysler officially boycotted all NASCAR races in 1965, although a few independent racers did compete with Chrysler equipment.


For the 1966 racing season NASCAR changed engine eligibility rules, and the Hemi engine was back. Racers found many ways to optimize the free-breathing nature of the Hemi heads. With the powerful 426-cid engine under the hood, stock-cars were seeing speeds of over 175-mph. NASCAR racers who had switched to the Charger body started experiencing rear end lift around corners on the high-speed tracks. "You would spin the tires at 180 mph going down the backstretch," said driver Sam McQuagg. This was due to air traveling faster over the top of the car than under it, causing the car to act like a giant airplane wing. McQuagg was the first to install a horizontal aluminum strip to the decklid of his Dodge Charger, improving traction and introducing the rear spoiler to NASCAR racing. The 1966 Firecracker 400 was the first race the spoiler was used, and helped McQuagg lead 126 of the 160 laps, including the final 30. It would be his only Cup victory.


By the end of the 1966 season, Hemi-powered stock-cars drove to victory lane a total of 34 times in 49 NASCAR events. Driver David Pearson and his #6 Charger finished first on 15 occasions, and would go on to win the Grand National Series championship, with Chrysler winning the Manufacturers Championship.


------------


Great Meadows, New Jersey, August 1, 1964 - Drag racer Don Garlits, driving his "Swamp Rat VI" Hemi-powered dragster, broke the 200-mph quarter mile barrier, clocking 201.34 mph with an elapsed time of 7.78 seconds. He would also win his first NHRA National title this year.

Dodge Charger 1966-1967


1966 Dodge Charger After Ford's successful debut of the Mustang in 1964, car manufacturers scrambled to bring out sporty new models. At Chrysler Corporation, Plymouth had just introduced their new pony-car, the Barracuda. To avoid competing with their sister company, the Dodge boys based their new fastback on a mid-sized car platform, which would provide plenty of room under the hood for their biggest and most powerful motors.


Inspired by the 1949 Cadillac, Carl Cameron designed the stretched roofline concept car, built around the intermediate-sized Dodge Coronet. Displayed at auto shows in 1965 with positive reviews, the Charger was put into production shortly after. Similarity to the Rambler Marlin was coincidental.

1966 Dodge Charger at car show Sharing the B-body platform with the Coronet (which had became Dodge's intermediate-sized car in 1965), the Charger's long body rode on a 117-inch wheelbase. Front sheet metal resembled the Coronet slightly, but the Charger's grille was wider, smoother, and featured fully rotating, electrically-operated retractable headlights. Helping the 3,600 pound car look sporty was the wide fastback which stretched all the way to the rear bumper. Chrome block letters spaced across the tail-lights spelled "CHARGER".


With a six-foot-wide body, there was plenty of room inside. Four individual bucket seats shared a full-length console. The rear seats and console pad folded forward, and with the trunk divider dropped back, seven feet of cargo space was available. Interior carpeting extended into the trunk. Four large, round pods housed the tachometer, speedometer, alternator, and fuel/temperature gauges. High-clarity electro-luminescent back-lighting, previously used on other Chrysler models, lit up the dashboard at night. Considering its mid-year introduction, the 37,344 Chargers sold in 1966 was impressive.

The Charger's base transmission was a column-shifted three speed manual, with a four-on-the-floor manual or three-speed automatic optional. With nothing but V-8's under the hood, a two-barrel, 230 horsepower 318-cid engine was standard. Optional were a 265-bhp 361 motor, a 325-bhp 383 engine, and a street version of Chrysler's 426 Hemi race engine.


426 Hemi Engine


cut-away illustation of the 426 Hemi-head The 426 cubic-inch Hemi motor was first seen in 1964 (see sidebar) and was offered in street trim in 1966. Cylinder heads with hemispherical, or hemi-shaped, combustion chambers are a good choice where power at high rpm is desired. The advantage is that valves can be angled away from each other and larger valves may be fitted. Additionally, a straighter, less restrictive path can then be provided for the air/fuel mixture, improving engine breathing. Placing spark plugs near the center of the chambers helps achieve more complete combustion of the air/fuel mixture. However, because the intake and exhaust valve stems point in different directions, cylinder heads need to be larger and rocker-arm geometry is more complicated than other OHV V-8s.


Huge by any standards, the 426 Street Hemi was nicknamed "Elephant Engine" not only for its cubic capacity and power, but for its 800-plus pound weight. With a 4.25 inch bore and 3.75 stroke, the seven-litre OHV V-8 was based on an iron block with four-bolt-main, cross-bolted caps. The crankshaft was made of forged-steel, as were the connecting rods. Compression ratio for the street Hemi was 10.25:1. Intake was an aluminum dual-plane dual-carb manifold, with Carter AFB four-barrel carburetors mounted in-line. With a solid-lifter camshaft, 425 horsepower was advertised, but actual output was closer to 500. Torque was listed at 490 lb/ft at 4000 rpm. Records indicate 468 Chargers were equipped with the Hemi in 1966, which cost the buyer an additional $880. Stiffer front springs and bigger 11-inch drum brakes were included.


Chrysler was one of the first automotive companies to offer a 5 year/50,000 mile powertrain warranty, but it did not apply when the Hemi option was chosen. Instead, buyers got a one-year/12,000 warranty, with a strict clause prohibiting any racing. Chrysler was quite serious about this; there are many reports of company representatives visiting race tracks all over the country, recording license plates and vehicle identification numbers.



1967 Dodge Charger


1967 Dodge Charger As for many second-year car models, changes were minor. Fender-mounted turn signals were the main visual difference between the 1966 and 1967 Charger. Inside, the full-length console was replaced by a shorter version, due in part to customer complaints about entry and exit from the back seats. Front buckets were still standard, but a folding armrest/seat and column shifter was now offered to allow three people to sit up front.


Options for 1967 included a vinyl roof, heavy duty suspension, towing package, and front disc brakes. As for engines, the 361-cid motor was replaced by the 383 V-8, in either 270 and 325 horsepower ratings. The 440-cid Magnum, Mopar's largest-ever production motor, became available this year. Based on the 383 RB engine block, bore size was 4.32" and its tall deck height allowed a 3.75" stroke length. In the Charger, it was offered with a single 4-barrel and rated at 375-bhp.


Facing strong competition from the Mustang and Chevrolet's new Camaro , only 15,788 Chargers sold in 1967. Dodge decided a major redesign was in order, and a second-generation Charger would debut in 1968.
