There has been a bit of discussion in regard to engine weights in this thread , so I thought I would clear the air with my 2 cents worth .

1. Mercedes SL600 ...........................581 lbs

2. Mercedes 450SL Iron Block..............540 lbs

3.Mercedes 500SL Alum Block.............452 lbs

4.Ford Boss 429 Iron Block Alum Heads..680 lbs

5.Chevy Small Block V8 in 60's 70's.......575 lbs

6.Chevy Big Block V8 Mark IV ..............685 lbs

As can be seen the SL600 is about the same weight as a small block Chevy, so should not have weight issues transplanted in a 380SL .

Some one made a comparison between the SL600 and the SL55 .

The SL600 is a twin turbo V12 and the SL55 is a blown V8 , they have almost the same power ratios except the 600 has more torque but with more weight and a turbo, instead of a blower .
