Heard from someone that the Mancini rockers are identical to the Crane gold but I cannot get more info. If anyone has experience with those please let us know As usual thanks for the great help
email Harland Sharp and ask. I emailed them about fulcrum length on the Mancini rockers and they gave me a good reply. They even mentioned that the Mancini rockers are a copy of the Crane rockers. I was emailing about small block rockers though. So perhaps just email to double check...
