A couple of questions - what do you mean by hippo roller?? Do you mean high performance? Would you advise a steel billet cam and the best roller lifters I can find? I've heard about a company that makes roller lifters without needle roller bearings, just plain bearings like on a crankshaft.
hippo hi pressure pin oiling .helps put more oil on the roller pins. the ones with no roller bearings are made by isky all solid rollers cams i have seen are steel cores .the lifters i listed have roller s bearings and them are the ones that i have used with hippo you get more oil were you need it
