So I’m preparing to do a stock 1994 5.7L build, my very first engine build as a matter of fact. The block is sitting in my garage, boiled, blasted, machined, honed and painted, waiting for parts.
I’m sure this has been discussed numerous times here in different contexts and I’ve reviewed a lot of opinions in a lot of forums but I’m still really indecisive on what bearings and rings to use in this build.
My understanding is they tri-metal is better for performance use but less forgiving on embedding any particles that make their way into the bearing, while bi-metal is better suited for street/daily use and more forgiving with embedding… this lead me to select Bimetal. Soon after I read that aluminum bearings are iffy and I shouldn’t used them, but all the numeral bearings I see on rockauto are aluminum?
At this point I’m just looking for some guidance. All I want is for this engine to run and have a smooth break in so I can do regular old truck things with my regular old k2500. Advice?
