I have a 426 in my shop thats been through hell. It dropped a valve and the previous owner had it rebuilt. The original shop never looked at the engine to determine why it failed, just replaced the parts and sent him on his way. Well the engine did the same exact thing a few hours later and the owner took it apart himself. He found the valve stuck in the piston and set it aside, sold it a year later to someone who brought it to my shop. It has been sitting here for months since I cant find cheap parts for it readily (was trying to not kill the guy on parts) Now I am trying to find a new used motor for it, or in the least a crank that is half cheap but I cant find anything 426 other than brand new. Anyone know if the cranks are the same or compatible in any of the other years?? Anyone have one they want to part with? otherwise I need a whole motor. I can get a new hotrods crank complete in budget, but need to know if it will work.
