Do you have a Roosa Master injection pump like a late 770 or 1550 does?

80 hp is going to be tough on a 77 diesel without throwing a turbo on it. The roosa master pump will help, 1550 pistons and sleves will increase the displacement. can you install a 7 main 283 or 310 in the tractor, 80 hp will be no problem.
