I have a Blown 6/71 Ron Grose 496 BBC 966HP that I just bought from Folsom Cali! I live in Idaho and will be running the boat at 3055' elevation, it has 2 Holley 830 blower carbs 4150 80509 2. It's set for sea level, what would be my base primary and secondary jets at this level? It's running 6lbs of boost .0020 valve lash (hot) solid lifters, 29 degrees timing? Any help would be much appreciated!
