V8 Conrod Positioning:

In a correctly built Holden red/blue and black V8, 4 of the conrods face rearward and the other 4 face forwards.

Correct Holden V8 Conrod Positioning:

Holden red/blue and black V8 conrods are installed as follows. Conrods 1, 3, 5 and 7 have the machined tab on the bottom of the conrod facing the *front* of the engine. In other words they line up with the notch in the front of the piston. Conrods 2, 4, 6 and 8 have the machined tab on the bottom of the conrod facing the *rear* of the engine. In other words they face *away* from the notch the front of the piston. They *don't* all face the same way like they do in a six. A noticeable jamming of the engine occurs if this has been done incorrectly.
