Hi,

I do not have information for the 1074cc engine but the 1500cc engine has the following values:

Cylinder Head, 7/16 BSF size, 58...66 lb/ft
Main Bearings, 7/16 BSF size, 58...66 lb/ft
Big Ends, 3/8 BSF size, 33...42 lb/ft
Flywheel, 3/8 BSF size, 33...42 lb/ft

If the screw sizes are the same in the 1074cc engine you could probably use the same values.
