I lately ran my car and manally shifted it at 5000 to 5500 no problem it seemed it would easily rev to 6000.Its a 400 rebuilt but I don't really know anything about the motor.It seems decently strong.I got a 15.1 at 96mph with a 2.47 60ft actually three runs all super close to same .I have 3.08 gears and am at 1900 feet above sealevel.Was talking to buddy at speed shop and he thinks the pontiac 400 stock woudn't rev anywhere near that high..is he right..car might have slight lope but not that bad.idles pretty smooth but hear you can have a pretty good cam in these cars and still have smooth idle.

CE subframe connectors.
