I have a 1956 235 from a belair. Going in my 1950 pickup with original 4 speed. Reusing the bell housing from old 216 so motor mounts will work and starter
Questions
1- replaced the pilot bearing with a dorman 690-034. It just goes right in and spins around. I remember how hard it was to remove the old one. Should it be this loose?

2- how important is it to check the runout on bell hosing?
Was hoping it is not too big of a deal as I don’t understand the shop manual about how to do it

3- does bell housing get lock washers on the mounting bolts?

Thanks in advance.
