SV Engine Specifications
Engine specifications for the IHC SV line of engines.
- From Bill Thebert – BinderBulletin
Please note the different years in the headings by each engine model. Note that by 1979, for example, emissions equipment had reduced the HP output of the 4-196 to that of a 1974 vintage 4-152.
