I've been wanting to do this mod to my '94 E420.

What are the performance gains? Real world numbers.

I think that the 3.07 might kill your freeway mpg, if you care. But then again, it'll give the 500 a good run. Heck, why not put in a 3.27 (?) from the W124 wagon?

Seems like a 2.82 like the one from the 500's would be better.

Thanks,

Craig
