V8 engines tend to be larger bore and shorter stroke than an inline 4 or 6. The length of an inline engine can be shorter if the bore tends to be smaller. Inline engines tend to have longer strokes than V8 engines for this reason. Because most V8s are "over-square" with a larger bore than stroke, they can usually be revved to higher rpm limits than their longer-stroke cousins. An old M or SM engine tends to hit its torque peak at a much lower rpm than a comparably sized V8. There have been some nice looking installations of IH V8 truck engines in Farmalls, but they won't lug a heavy load at 1200 rpm like the old 4 cylinder engines would. On the subject of the M rear end, it will generally handle the increased power quite well unless the tractor is weighted heavier in an attempt to pull a bigger load, or the operator insists on doing heavy tillage in 4th gear.
