There can be issues with Rover V8 flywheels. Our experience is that there are variations by 13mm in the length of the crankshaft where the flywheel fits. This needs to be checked out, and the fit of the starter pinion. There can be issues with entry of input shaft into bush and spline engagement in clutch plate.
