    Not sure what block numbers are high nickel content. In the past, I have used mostly 010 blocks and they have worked out ok. Any subsequent builds I do on a SBC will start out with a Gen I roller block or short block. I don't know all the applications for these motors, but do know they were used in '89 to '93 Caprice and can be identified by block numbers 148, 548 and 638.

    Starting with a roller block and one-piece seal just makes way more sense than spending big dough to convert an earlier flat tappet block to roller cam.

    Now, I might change my mind if I came across a good 400 high-nickel block.....
