So, the M113 is the same engine that is the base for the E55ML, which
is M113 Supercharged outputting 493 hp and 516 ft/lbs of torque. Now,
the question is, what is meant by based on the M112? Does this mean
same size block physically but bored differently, or the design is the same
with respect to routing of all the various plumbing circuits and lifter
components, but bigger? I guess this is rather un-charted territory and
I better start doing some serious research. If I find this might be, in any
way, possible, I'll add something to this thread.
