Does that apply to the splayed main caps also? I thought that was why they offset the outside bolts and angled them to an area that was thicker. Not arguing I just don't want to do this twice and already have the main kit.
Yes. No matter where you put that outer bolt there isn’t enough material for it. That hole makes the block weaker. Now you stick a bolt in there and load it and it’s even worse.
Every dedicated race block Chrysler made and the Ritter block ALL use straight, 1/2 outer bolts. They did that for a reason. And they made that area of the block much stronger to take that load.
