Mercedes-Benz W109 6.5 (6.3) 300SEL
1970 Mercedes-Benz W109 300SEL 6.5 (6.3) Description:
The W109 300SEL 6.3 marked Mercedes-Benz "unofficial" return to racing after the 1955 Le Mans tragedy with a brief, but successful racing history winning at Macao and finishing first in class at the 1971 24 Hours of Spa and 2nd overall only because the W109 required extra refueling stops in spite of its 30 gallon fuel tank. The W109, fondly referred to as the "Rote Sau" (Red Pig), heralded the beginning of AMG.All of today's AMG 6.3's trace their ancestry to the "Rote Sau."
The extensive restoration of #4632 commenced In 2006 and was completed in 2012, however, there has always been constant tweaking and improving.
#4632 is a rare non-sunroof W109.
There are too may items to list here, however, all work is documented.Since the completion of the restoration, #4632 has been driven just under 10k miles with trips from New York to Miami.#4632 is fully sorted and reliable.#4632 is normally driven on a weekly basis.#4632 IS NOT AND NEVER HAS BEEN A GARAGE QUEEN!#4632 is garaged in an environmentally controlled facility.
The interior retains the correct rubberized horsehair padding with NOS Mercedes-Benz hides resulting in the correct, fabulous Mercedes-Benz fragrance.For additional safety, modern inertia shoulder/lap belts are fitted.All original interior Zebra wood has been refinished by PebbleBeach winner Dave "Mountain Man" Chamberlain and is magnificent.
The M-100 engine was rebuilt to generally accepted racing specifications consisting of OEM Hi-Performance Mahle104.5 mm high-compression, flat-top pistons which have had a Sanford Hard Coat applied whilst retaining the Mahle molybdenum coated rings thus increasing displacement to 6.5 liters and increased compression.A set of NOS camshafts were re-profiled by Crane to be a bit more aggressive and result in an estimated dynamic compression of about 10.5. The car idles perfectly with just a bit of a lope. Chevrolet big-block valve springs were substituted as they were a perfect fit and are progressively wound. Special alloy Technovance valve guides were installed.The cylinder heads were milled and flowed, however, it was found that there could not be any significant improvement over their original factory design, so all that was done was a little polishing and a 3 angle valve cut and lapped to the hardened seats.All rotating and reciprocating components have been balanced to within 1/2 gram.
Fairchild Fuel Injection Service rebuilt the Bosch mechanical timed fuel injection to accommodate the modifications to the M-100.
The Bosch electric fuel pump has been replaced with a modern and super reliable MSD/Mallory Comp140 Series positive displacement gear-rotor pump.#4632 has previously sat for more than 2 hours in 100°+ temperatures in Manhattan traffic with the A/C on whilst experiencing no vapor locking and engine temperatures never exceeding 195°.
Exhaust manifolds have been Jet-Hot Performance coated with silver ceramic and a complete stainless steel exhaust system (including resonator and muffler) has been fitted.
The dual point, mechanical advance Bosch distributor is retained, but has been converted to a modern optical trigger unit.
The K4-50 transmission was rebuilt by Import Performance Transmissions and shifts almost as fast as today's "double-clutch" transmissions.
The driveshaft has been completely rebuilt and balanced.

Another of the more advanced aspects of the W109 is its self leveling air suspension — the forerunner of today's Airmatic system. Four air chambers with bellows replace steel springs, pressurized at up to 228 p.s.i with a re-circulatedalcohol/air mixture fed from an engine-driven compressor. The system operates correctly.
New stainless steel brake lines were installed with a new 19mm dual/master cylinder and vacuum booster.All calipers were rebuilt and new correct ventilated rotors were fitted front and rear.EBC organic pads are fitted.
A ZF limited slip differential is fitted and incorporates the OEM oil cooler.Having full independent suspension with anti-dive technology the 1968 & 1969 W109's were the first production 4 door automobile incorporating 4 wheel ventilated disc brakes.15" alloy Bundt wheels are fitted with P205/60R-15 90T Yokohama Avid T4 Tires.#4632 has been retrofitted with Koni adjustable shock absorbers.The original like-new Bilstein units are included with the extensive spare parts package which will be included with #4632.The handling qualities of #4632 exceeded many sports cars of the era and many of today's cars.
The original Hella H4 lighting assemblies are retained and have been converted to HID Bi-Zenon.
Although #4632 is titled as a 1970 model year, it retains all of the unique1968-1969 features.The approximate empty weight is 3,700 lbs.Time from 0-60 MPH is 4.5 seconds. Top speed of 162 MPH @ 6000 rpm.
The technology of the 1968-69 W109's was considered "science-fiction" as it was literally light years ahead of any other vehicle of the day and this marvel of engineering was accomplished without computers or microprocessors, but with slide-rules, imagination and passion. These amazing machines that once prowled the autobahns are today a rare sight, yet they would remain as the world's fastest 4 door sedan until 2003 with the introduction of the Mercedes-Benz W211 E55K AMG (Beast).
#4632 always draws crowds of admirers at shows and events. Extensive car show display paraphernalia is included with the purchase of #4632.
Special thanks to Robert Fairchild, Dave Chamberlain, Star Motors NY, DB DepotGermany, Tony Rudder of Top Flight Motors and the late Bruce Kirner all who helped bring this amazing machine to life.
