The traditional hashness of 2 bearing Seven engines is hugely influenced by clearance of main bearings (even the smallest) and by spark advance. A box saloon will be blessed with manual advance. This must not be more than necessary for performance, and a litle of that is best traded for long crank life. With new bearings and less harshness have to be careful to moderate advance.
Any observations of the replaced bearing would be of interest. Precisely on track, what thicknes of shim or paper can be freely rolled over? Can you asses the depth of the worn track in the outer ring?
Tracks and rollers should be shiny bright; often matt grey. Track should be close to centre of ring.
The recent threads Front Bearing Puller and Engine Strip Down relate. (Also Alternative Crank Bearings)
