- I've heard that Jerry Hathaway recommends removing a mil or so from the connecting rod big ends to improve crush on the bearings. Brucem 19:48, 23 July 2008 (EDT)
- John Titus has demonstrated the feasibility of using main bearings from a Ford V8 (351M/400M) engine in place of the expensive ($800 ++) Vandervell main bearings. The bearings fit the SM crankshaft out of the box. The block must be line bored to accept the Ford bearings. No other modifications are required.
