Hi guys can anyone tell me what the difference is in the counterweighted crank and the ordinary one and which is better for a performance build up.

Personally I would use the red crank as it is lighter, therefore picks up revs quicker, and with a dynamic balance the torsional vibration issues are relieved.
Remember Bathurst was won by Brock in a Torana with a red 202. |

I disagree. The blue crank is much better for street use as it allows for better torque production which is what you want for the street, regardless of how high performance you think you want it to be.

Hi Dave.
It's only the 3.3 (202) Blue motors that get the counterweighted crank and the thicker balancer. The 2.85 (173) gets the plain (shorter stroke) crank and the thinner balancer. With so many balancers being replaced by inexperienced mechanics ov |
If at first you don't succeed, just call it Version 1.0 |
