I had the almost exact set up in my 73 nova years ago and it had a comp cams 292 magnum then later I put in 305 cc magnum, both are hydralic so set it once and forget it, very low maintenance which I liked in a street strip car.
They both had a really nice noticeable lopey idle and pulled like a bat out of hell from off idle to 6500+ rpm.
Lunati also makes a great compareable cam, called the bracket master cam which is also hydralic. here's a couple links to the above mententioned cams.
