Next trap (in more ways than one)....The Crankshaft. Read the posts about the crank, the types, the differences and the most important single factor for good engine performance, bearing life and the abilty to ride home rather than on a tow truck, with a rod through the case.
I will step aside to allow a fanfare to sound, the curtains open, and the spotlights shine on........an important announcement from an esteemed member.
Additional... Accepted practice these days is to grind the crank main bearing journal just to clean up, rather than sticking to standard undersizes, thus increasing the number of possible crankshaft main bearing regrinds. Choose a smaller undersize solid one piece bush and fit to the case, then line bore the bush to the running clearance. All detailed on the Forum. The bush housing sometimes suffers damage and ovality, remedy here is line boring the case and a custom bush. Leakage here, between bush OD and case, obviously lowers oil pressure on the pump delivery side.
Camshaft and other simple plain Bronze bushes should be of commercially available standard types. Possibly just needing drilling an oil hole as required. Some pattern parts come with internal scroll oilways, most don't. Heat the cases, as usual practice, bushes should come out easily. Blind camshaft bush removal can be a conundrum.
