Sylvester,
930/10, is from a 81/83 Rest of the World 911SC. It is rated at 204 HP, as compared to 180 HP for a US '79 911SC.
The compression for a 930/10 is rated at 9.8:1 vs 8.5:1 for a '79 US model.
The 1980/83 US model 911SC was rated at 9.3:1.
Looks to me like you'll need premium fuel for that euro motor.
