Its not real deep but kinda big, enough for the crank to hit it. The last time it run was in July and it wasnt doing this. My dad is pretty sure that if I get the dent out it will be fine. I hope so because its been down forever. The motor hit the k-member a couple of times during the process of fighting the lt's, so I think thats where it come from. Other than that, the build went great other than no cams. I'am getting ready to go to my dads to work on it so I'll let you know how it went. Thanks for the help.
