M113/M113k BLOCK/HEADS difference

Good morning! I am looking to rebuild the M113 as a supercharged version. All internals and supercharger would be aftermarket, and therefore replaced.

Being that it is much less expensive to purchase an M113 than an M113K, ($300 compared to $3000), and as I am going to remove everything anyway, my question is, do any of you know the difference between the actual block and heads? No connecting rods, etc. etc. just the physical block and heads. Are they modified for the Kompressor in which case I am smarter to buy an M113K to begin with? Many thanks!

Welcome to the forum. The M113K was installed in a lot of models over the years, but moreso in the W211 E55 platform. Therefore, there continues to be more traffic on that page in the forum than any other. You will likely get better and faster answers there than any other portion of the forum. https://mbworld.org/forums/w211-amg-81/
