    Im replacing mains and took a compression test before tear down. Is 45-50 lbs normal for this motor or should I do rings also???

    Doing a compression test on this engine is kinda worthless because of the ACR (Automatic Compression Release). Your best bet is to get the shop manual for the engine and check the different specs for this engine.
