piston questions

And yes. For the cam I already figured on sending one to Ken at Oregon. Which brings another question. I want to run a mechanical fuel pump. I know I have a a couple of magnum cores to send in. They're already a roller cam. I think I have an old LA cam somewhere in my stash so I won't need the Hughes cam extender for the eccentric. Can an original flat tapper cam be reground into a roller cam
no a flat cam can't be ground into a roller cam. you need like for like cores on them.
