Don’t forget the weight of the crankshaft just in case they will be going to Indy for the first time!

Larry, where would one get the weights on the crankshafts? NHRA doesn't
list them on Blueprint Specs, and Dwight doesn't have have them listed. Never has. Thanks, J.R. |

I’m not real sure. A core supplier would be a good source. We used to grind crankshafts and would ship some but most of them were hurry up we need it by this weekend. And I still have some waiting to be picked up and we closed the business over 25 years ago.
The AERA would be a very good source. Hope this helps. |
