Has anyone got the relative dimensions for 215 oil pump gears, Rover SD1 gears and Buick 455 gears. I know a friend fitted a Rover oil pump cover to his 455 but promptly melted the bearings due to starvation. My, probably mistaken, thinking is that the Buick cover has bigger oil passages and also it has larger gears. As the pump covers interchange the gears may be the same diameter but taller in the big block application. Can anyone help with dimensions or pictures of the relative sizes.
Thanks
Alan
