  • Oil Pump

    Ready for final assembly of my engine. The oil pump I have is a slot drive for a 1275 A+ block along with a cam shaft that matches up with this pump. I am bolting this up to a 998 pre A+ block and these blocks have has three tapped holes. The pump I have currently has two hold down holes in the pump. Do I need to get a different pump or do I drill and tap an extra hole to fasten it?

    I seem to recall that large bore engine (1275) oil pumps have a different depth than small bore (850/998/1100) oil pumps so they're not interchangeable. I put several A-series small bore oil pumps in the White Elephant Sale last January so someone in the club may have one that they would be willing to part with.

    If you can afford the car, you can afford the manual...
