Aluminum block thread repair
I would like recommendations for repairing the threads in a 1983 380 SEC 116 V8 aluminum block. The block has some threads already repaired with helicoils and two that appear to be timeserts. Two of the helicoils partially unwound during disassembly and I am considering repairing with Helicoils or Timeserts. I will need to purchase a kit for
either one. Does anyone have a recommendation?
