Of course some 318's and 340's had forged cranks, but no need to go look'n if he has one sitting in his lap... especially one with the right pilot bearing....
This is a long time project because the garage is occpied by my restoration of the Meteor ยด59. Therefore I was planning to build the Barracuda-engine while driving the Barracuda, therefore a need two cranks. Otherwise I think the 273 would get the job done.
But where do I find the adaptors between the A-833 and the 318 crank?
