Most of metal in center of plate is removed for weight reasons. Yes, oil pan bolts hold engine to plate, same as on the engine I've been flying for 8 years on the -4. BTW, the oil pan bolt holes should be tapped to the bottom (using a bottoming tap) for maximum thread engagement with the longer bolts used. I have no worries about the 26 bolts through oil pan being adequate to do this job. Yes, plan to use the stock oil pan or possibly an aluminum pan made by Conversion Concepts if there is a weight advantage. Tracy
