My Oliver 880 has a Bosch pump. I was told by 1 person that if I change to a RoosaMaster pump it would have more power. Can I use the same injectors?
Opinions or suggestions. Thanks.

Don you can use the same injectors. You will need the roosa pump, two gears, the front plate and backing plate, plus the injection lines to make the swap. You can find these parts on a late 880 or 1600. I converted my 880 to a Roosa setup, the power increase is noticeable and throttle response is more snappy. On my 880 I had to do some grinding for clearance on a bracket forged into the block. Not sure if this is necessary on all 880s.
