You can run a properly tuned 10-1 motor on 94 octane from Sunoco. Their fuel has a actual rating of 95-96. The lead additive should be used for valve lube to prevent seat recession and as an added buffer to the Sunoco 94.
You do not need to mix if your timing and distributor are tuned and you are at an actual 10-1. Check cranking pressures as well.
Simple questions deserve simple answers.
If you read through this thread you will understand that things aren't always so simple. It can be simple if you do have access to the high octane fuel. Greg asked for the lead study because he didn't have that luxury living in Springfield, MO. He's running a 428 with higher than 10-1(read) which further complicates his situation.
