408 - Crank hitting dip stick

I finally got my new 408 broke in, Still chasing a few problems down but had it ready to take around the block a few times. After about a mile started hearing a bad noise, Got it home and found the Crank was hitting the dip stick. Pulled the dip stick and it was almost Z shaped from where the crank had hit it about 8 inches up. Fortunately just bent all up and nothing I could see broken.
My worries are it was not doing this at all during the break in process or any of the testing over the past week I have had it running. Also once I straightened out, it was not hitting any more but I am worried it will happen again and do some damage.

Is this a common problem with Stroker Motors? I was considering cutting off the dipstick to plug the tube without it extending into the pan and carrying a second dip stick to use for just checking the oil.

Anyone else seen this problem and have a suggestion?
