on 65 cam bearings were added

on 65 they added a "D" prefix, and it lasted in production up until the early 90s (not sold in the US of course, but we the rest of the world did get 1200 after 65)

that's not true, the early 1500s in the earliest type 3s and 1500 buses were more or less stroked 40hps...but a H case DOES have insert cam bearings, just as all post-65 engines

just to add, H0 and B0 cases are not the best in terms of longevity, specially when it comes to performance engines, dual port engines recieved a much better quality alloy.
hope this clarifies this a bit |
