302 LX Eric:
My compression works out to 10.25:1. I run 100 octane fuel. I could get away with 93 but I'm running 24 deg. inital timing & lots of fuel taken out with a PMS. Before anybody says I'm nuts with that much timing, the car was professioanlly tuned on a dyno with an air/fuel meter.

All:
The point I was trying to make earlier is trying to say what motor will last depends on the build. The big problem with the earl 347's was the ring location. Most builders have solved that problem. It alos depends on how hard you push it. Many poeple get 150K+ out of a stock 5.0. Mine lasted 56K. My experience was that rpm was a bigger killer than hp.
