Gear Differential Question
I have done some research through over 50 pages of posts about changing gear differentials, but i still have a question.
Here is some background info:
I have a 77 Euro 350SLC with an automatic tranmission and a 3.46 differential.
The low end in the car is so powerful, i can burn rubber off my 8" rear tires. The acceleration is enough to pull my head back.
Not bad for a 20something year old car!
Unfortunately it takes 3000rpm to go 60mph, 4000rpm to go 80mph, 5000rpm to go 100mph, you get the idea.
I want to be able to get better gas mileage and to be able to go at high speeds without having to put such a high strain on the engine. I don't mind sacrificing the low end performance.
A person from a well known mercedes dismantler shop told me all 77 USA 450SL / SLCs came with a 3.07 differential as standard equipment. He said i may no see much of a difference installing a 3.07, and he offered me a 2.47 differential from newer 500 / 380 SLs
The question is: which differential should i install?
3.07? or 2.47?
Will i cause any damage in the long term by installing the 2.47?
Any help in this matter will be appreciated.
Thank you all for this great forum.
