But when you read the magazine reports from the time it's pretty clear that's the shift point or where it goes to shifted. Peak is a bit below 6,000 (but of course depending on gearing we often want the shift to occur just past peak).
First thing I recommend is drive it and tune it, then decide what direction to take it.
You can find a lot of throttle response and HP just by tuning an engine - especially one that has been hot rodded.
Other things, like whether it has a good (useful) valve job would have to take it apart.
Photos will help us identify what you got. For example intakes are pretty easy to pick out just by shape and design.
It's almost certainly going to have 360 heads on it. Whether it was opened up for the 2.02 valves will be a question but I don't think it matters unless/until your planning a build and the cam can use that extra potention flow.
The casting numbers can be hard to read even on a clean engine as they run partially underneath the valvetrain.
