I just got my 383 back in my 62 wagon with fenderwell headers installed and we went to start it . It back fired and then when restarting the starter would not engage. We took the starter off and the hole for the outer starter bolt is cracked. Can this be repaired by welding? Its not cracked all the way through.Starter seems to be bad also and I will send it out I am more concerned about the block. Maybe heli arc can be done. Has this repair been done by anyone?
