piston ring and main bearing help!!!

you cant go wrong with Clevite bearings, they are an industry staple. what pistons are you running? Sealed Power are good as well as Manley if they have them for your piston application.

i have been looking at clevites, but they have so many different "series" i dont know what what are best from me

ive been looking at these

the build that im doing for a friend right now we are using Manley pistons and H Beam Rods, and got Manley rings and generic Clevite 77 bearings. were using all ARP studs and OEM gaskets. nothing too complicated, just proven parts that work.
