hello friends
time to choose roller lifters for a 650 lift fun street cam. will the 66284 work with a stock 440 block. i am told by one person they will but then another says they won't. the person that says they will not work says it is because stock blocks with solid flat tappet had smaller holes for oiling and the hydraulic flat tappet blocks had bigger holes for oiling. is this true? how would i find out and can i use the 66284in a stock 440 block? I have a friend that is willing to sell these so it is either a yes or bust.





Simply not true like Mike mentions. Now their production tolerances, thats another story in itself....
