1969 L-89 rebuild. Need help choosing cam
My dad is restoring his 69 L89. It's all original with the tri power. He wants to swap to a hydraulic roller cam and be able to run 93 octane. The stock aluminum heads are being reworked with hardened valve seats. He wants to keep it 11:1 if possible. Any advice on a cam profile ? Even if it needs a custom grind that's ok. Thanks in advance.
