Installing roller cam in 1979 302

[bourbon]

i thought the roller cam blocks had taller holes for the hydraulic lifters in them. well at least thats what i read. 1985 and up.

Bourbon is correct. The reason for the smaller base circle cam is not to clear anything but to keep from pushing the lifters too high and causing a loss of oil pressure. As I said before check with comp cams as to proper components.

This is correct. If you dont use a smaller base circle cam the lifters actually lift the dog bone.
