505 stroker starters

Just a thought. I know it may not be feasible, but on high compression Harley motors we use to build, there was a tool that allowed you install a manual compression release by drilling and tapping into the head next to the spark plug. You would depress the button on top of the compression release which essentially allowed the exhaust to exit and once the motor completed a few revolutions the CR would close. Many starters were sacrificed until this gadget was devised. Later on Harley developed the ACR (automatic compression release) that was internal and electrically activated. Obviously there are different reasons why on an automobile engine it would pose quite the challenge, but still you wouldn't need to have all 8 cylinders affected, maybe only 2 that would drop the compression enough. Hope this thought doesn't side track your initial question or hi jack the thread.
