my buddy is trying to get me to do my 454 with 500-700 hp and 10:1 or 10.5:1 compression on pump gas I don't know how well that will work but he is convinced we can do it safely.

This chart was made for a small block Chevy, so with a 454 you can use a little more cam than what the chart recommends, but only a little more.

The most important thing you can do for your new mill is to engineer the squish/quench to 0.035" to 0.045" to prevent detonation on pump gas.
