RE: cam mod |

I know this is late. But Crane and Comp both grind the original replacement also. If you're using an original HP 61 block, you'll have to modify the cam retaining system from the early thrust button style which had a tendency to allow the cam to "walk" to the vastly better '63 style with thrust plate retention. Easy for a machinist to do. BTW, the '61 HP tri power was rated at 401 horse. HP single 4V was 375 horse. |
