This is the pump to use for your "A" series engine for street use. this pump has the long vanes vs the short vanes of the 948cc pump. When trial installationis made,  make sure the vanes do not hit the block when installed w/o the gasket. If you do have interference, a little filing on the vanes or grind some off the block. You can use the gasket included w/o any gasket goop!
