I think you may have been referring to domestic small block Chevy stuff with four bolt mains. The RB block is super rigid with one piece style mains in a girdle. Fairly common on Nissans when the dual cam stuff came out.
fellas, thank you! my buddy says it's complete but his idea of complete versus my idea of complete have been known to be different. he tried to sell me to a car about a year but when I showed up with cash his daughter had the title (Comanche tag to boot) and he hadn't seen her "in a few weeks". Also, how do you wire in the overdrive?
