They all got bent out of shape because I prelubed a roller cam before I installed it and said since it was a roller cam I could have just used 10w-30 and it would have been fine. After building another guy a 1000 HP Magnum in a week for sema and telling him to go over everything before taking it to the track he got mad at me cause one of his driveshaft bolts worked loose. They are all knowing over in that crowd though so I left.
