* John Titus has demonstrated the feasibility of using main bearings from a Ford 400M engine in place of the expensive ($400 ++) Vandervell main bearings.  The bearings fit the SM crankshaft out of the box.  The block must be line bored to 3.1922/3.1930 inches to accept the Ford bearings.  No other modifications are required.  Ford bearings are available in STD .010, .020, and .030 oversize.  Be sure to use FULL GROOVE bearings (Clevite MS981P or equivalent).
