/6 differences

Actually, that is the reason I ask. We own a Hesston Swather that has an HB225 six in it and I am thinking about finding a slant out of a car or truck and swapping them. The exhaust manifold is cracked on the HB225 and it has a variety of other problems so I was just going to replace the whole thing.

Do you think a different camshaft would be in order, or do you think the automotive grind would suffice?
