Anyone have any experience with these cams on a 4g63?? They are supposedly made in Australia. My engine builder is offering me these as an alternative to Crower 64414's as he is still waiting on the Crowers. He said the Lazer's cost more and have a bit more lift. I'm thinking I'm just going to wait for the Crower's. My spelling could be wrong on those cams. There is a Lazer cam website but it's from the states and he said they don't have a website as of yet.
