Since my new engine will be a diesel (Cummins 4BT), vacuum units are out. Diesels don't make vacuum and I don't trust the aftermarket vac pumps. That leaves Hydroboost as the best option. Looks like the larger Ford & Dodge diesel trucks might make good options. Later model pull outs are plentiful and they are fairly cheap & easy to rebuild.
Has anyone here tried installing one of these units?
