Thanks for the input. I actually picked this up used from one of the grand prix forums. I knew it would have some wear marks since it was used, but the one groove had me concerned. Seller swears it is fine, but I wasn't sure.
If it was lobe, then i'd say get it polished out / reground possibly if could get it done for cheap. And could possibly
make up for any major change in a custom pushrod. But even then, I'd still just go with a new cam.
