While I have not personally worked on a 426 HEMI, I can honestly say I never heard of grand dad ever saying he did or needed to do anything for an oil pump to help it start up oil flow. He is pictured below (right side) with his race car. I’ll listen to him first before I follow any internet mumbo jumbo.
