Hello all, after an unfortunate accident my car and engine block were damaged, I am presently in the process of rebuilding both. I have since secured a brand-new block which is now at CSS waiting on the CORRECT pistons to be delivered to them. Together with the CSS work, the build will feature CP pistons and Rods, ARP head studs, upgraded cams and springs (not acquired yet), S55 oil pan and oil pumps. S55 dual HPFPs (which I may upgrade now), S63 injectors, EOS intake manifold and a set of Big Boost upgraded S55 twins! it will essentially be a cross between the N and S55 engines. I have not purchased any bearing sets yet because I cannot decide which to get as I do not have any experience with upgraded bearings, so I need your input, can anyone help?

Unfortunately I dont have any advice besides King bearings is what everyone has told me. But were kinda going through the same thing. I was planning on a N55 build but just happened to come up on a S55 long block... Im debating on which motor to use but really hoping the S55 is gonna be possible within reason. Ill follow this for sure and share any advice I can...

The thread for my project...

Also in the process of a forged build. I’m using ACL coated and extra oil clearance main and rod bearings, ARP2000 head studs. My builder is gonna order the head gasket. MLS from cometic.
