The SC cams will need the drive provision for the turbo oil pump. On the '76 3.0L engine this is simply a pin and not a boss as used in the later 3.3L engine which also drives the air pump. Other than that it is plug and play. Timing of the cams is personal preference based on how much torque you want to dial in at lower RPM. Cams need to follow and complement the build and turbo power band. With the mods you list SC cams have a great complementary grind. Should you go further with mods or wish to push the build more towards HP with less emphasis on low end torque other grinds become a better choice. It gets really involved, this is a simplistic answer to your question.
