Engine specs ???

[bostonbmw]

I am looking for info on factory specs(Bentley has nothing on the bottom end):

Main journals
Rod Journals
Pistons
Bore


Thanks Brian

Main clearances: 0.0008" - 0.0022"
Bore: 84.00 mm (total acceptable wear - 0.15mm)
Ring end gap:
1st ring - 0.1 - 0.3 mm
2nd ring - 0.2 - 0.4 mm
3rd rings - 0.25 - 0.5 mm

Don't have the rod clearances in front of me or the piston pin clearances.
