A little slow on your post. Sorry
I agree that it would need a new Tchain and oil pump and while I'm there I thought I would do the water pump to and am trying to decide how far I want to take it but might just go throw the hole thing (mains, rings cam baring ect) but will go one step at a time as its a winter project.
dose anyone have an opinion on the '78ish (need to look at the casting) BB 400?
I have one sitting in my shop on a stand and cant decide what to do with it just yet.
