A little different "Spin"" on your comments regarding starting without
oil pressure. An accusump certainly sounds like a viable solution. An alternative to that is a small button (normally open)used to create a momentary ground(when pushed) in the primary side of the ignition. This is pressed to eliminate ignition while the starter is spun until sufficient
oil pressure is obtained then released, allowing the ignition to function normally. Used this method on 302 Chevy in friends Can Am Car years ago, and seemed to work ok. Carried same application to 1600 Twin Cam Ford in Lotus serving street duty too. This worked for us.
