i think 3.4 would be stronger, due to thicker cylinder walls.

This is not correct.
The M104 E36 AMG with HFM from 1993>1997 used the 350SD crank (modified/Lightend)
The M104 3.4 AMG with KE from 1989>1992
Starting with the Win number in a W124 like this = WDB1240311B
Usen the W124 300D crank and not the 350SD crank.
The engine had also rebores to 91,5mm from the org. 88,5mm together with the 300D Diesel crank with the longer stroke of 84mm it gives the engine a volume of 3310cc. as they called 3.4
En Europe called (300E-24 - 3.4 AMG) has 272HK/6500 rpm. and 330Nm/4500 rpm.
This is mixed up by many around the forums becuase they canīt figure that the 300D crank gives 3.4 litter, but the truth is that the M104 3.4 AMG 1989 to 1992 was only a 3.310 litter engine but they called it 3.4
it was first with the M104 from 1993 and the HFM injections system that it came with the crank from the 350SD
The 3.6-24 brabus that I got with the M104.980 engine and KE system.
Has itīs own crank with 90mm stroke and a bore of 92mm giving it precise 3600 ccm.
But they cylinder wall are therefore very thin and thatīs why you should not use the brabus headgasket as it is 93mm in the bore and therefore you can use the headgaset from the 3.6 AMG witch is 92mm bore in the gasket and this headgasket keeps tight due to the thicker gasket between the walls.
I have done my own totaly rebiult of my brabus engine and has done a lot with the W124 3.4 AMG as well. so i know these engines very well.
