John, I had a 427 cubic inch SVO motor with 11.3:1 compression. I tried starters from CSR, Powermaster and Meziere. The CSR and Powermaster struggled when hot whereas the Meziere spun the motor over easily; hot or cold. Even when cold, the Meziere spun the motor at a much higher RPM than the others. When you hold it in your hands, you realize why it's expensive. I also required a modification to the nose piece of the starter and Meziere was happy to handle it for me, as the starters are made in-house at their facility in California.
