Well, I just broke my 360 block. Terminal?
I'm on the fence here. I'm not a fan of anything being weird in the mains or oil feed passages. If this was going into a soccar mom's car maybe, but if it's going to be abused the potential exists for a bigger issue after it's assembled. But, the act of fixing it will cost s boatload to weld it and remachine the areas affected. I've had to remachine a second 340 block after a crack missed in magnafluxing was found. 360s are cheaper to find...lol.
