great book, has me convinced that I'll be able to pull my B40 motor and be able to put it back together!
Yeah really good book, it has convinced me I need more expensive bits
... anyway most things will swap with a bit of work, except head and barrel..... so B50 cam, CCM rod, B50MX piston and liner just went on the list along with short push rods to get 11:1 compression. Plus a few detail things like cast iron oil pump and engine breather mods.
