Hmm, both these shortblocks have cams in place.
I may have to see what they look like as we seem to have a consensus the factory cams live longer nowadays.
Be nice and simple if the cam in th eblock I want to use is still in good shape!
Just a new set of lifters and go. Lots of assembly lube and good breakin oil anyway of course!
