Jay Leno to cram SLS AMG's V8 into 1969 Mercedes 6.3

Ask us to pick our favorite Mercedes-Benz products of all time and towards the top of that list sits this: The 1968-1972 300SEL 6.3. Introduced at the 1968 Geneva Motor Show, the original 6.3 was the product of one rogue Mercedes engineer who took the 109-series Type 300 SEL sedan and shoved the Type 600 limo's 6.3-liter V8 underhood. The heart transplant was good for 250 horsepower, allowed the Teutonic sled to rocket to 60 mph in 7.4 seconds, top out at 136 mph and made it the fastest road-going sedan of the time.

Not only did the 6.3 out accelerate the Porsche 911 S and Jaguar E-Type 4.2, with it's pneumatic suspension, anti-dive control and four-wheel disc brakes, it could dance as well as it could surge. And of course, Jay Leno has a 1969 example parked in his So. Cal. stable.

During a press event earlier this month, Jay and the Mercedes crew held a little soiree at his "shop" and revealed Leno's plans to swap in the 6.2-liter V8 from the Mercedes-Benz SLS AMG into his 40-year-old sedan. The union of the 300SL and the 563-hp AMG-fettled mill apparently has Mercedes' blessing, as the automaker's engineerings are helping Jay with the swap. Naturally, we can't wait to see and hear the results, and we'd expect a video of the reborn beast to be up in the coming months.
