Standard bore LCB (1-3/4"id) that is ideal for very hot small bore engines, for standard to high performance 1275s, and for street 1380s. The best quality production manifold, comes complete with 2 Y piece clamps. Also it comes with a stiffener bracket to attach to power unit

This can not be used on cars with rubber universal joints, it can be used on any size engine running either hardy spicer or pot joint diff outputs. If you are running rubber joints you need the 3-1 freeflow. It may be a bit close to the battery cable on 850 models but a bit of heat and bending should fix that!
