Is it ok to helicoil these or do they need to be welded up and rethreaded ? The threads were pulled out on several when the crank broke, on Dart Pro 1's if that matters.
No, its a motor i just bought, it had a scat 4340 crank and an ATI damper.Thats the second Scat crank i know of that has broke. Did not hurt the Little M block or the damper, just head and valvetrain damage.Needless to say, i wont use a Scat crank on this build.Is this your fesh 400?
I dont want to ask but did you have a TCI or Fluidampr balancer?
