Once we cut the roller lifter apart and push it enough out of the way to pull the Cam shaft out and then push the lifter into the cam location to get it out without any damage, I will measure the cam journals to see what they measure on the cam shaft. Motor ran good with a main stud laying in the oil pan 870s and the roller bearing gone away on one lobe. Cam is still good but this Indy block has been a pain over the years. Might take a few weeks.
