Hi, this comes to mind from time to time as I do have the 117 5.6 crank waiting. Although I posess one E60LH
and one E50 motor soon converted + two 119 974 motors, quriosity is allways picking me.
Now what block to use, well I somewhere read, Brabus I Think did one maybe more 6liter starting w a 4.2 block.
Also knowing the MB philosophy they are/were less likely to construct separate lines of casting when they
took the step by modifying the M119 block internally and shorten it also to enabeling the 4.2 shortstroke build.
The 6liter adventure I belive was not in the equation but as it did have, the closed deck i.e so much meat in it
AMG took the advantage to overbore and stroke it to 6liter.
Look at this 4.2 block and I guess it has enough to do a 97.5 max 5liter overbore, if you look closely, that
line beside the bore left by the gasket is 100mm dia, I Think 100mm is possible and as we know,
the problem is finding suitable pistons and building new headgaskets.
Conclution; a 5.6 could be built std 97.5 std gaskets 117 crank this will call for custom rods
made slightly shorter. Roger
