I have done numerous BBC conversions on 4X4's and always just used the small block mounts, I will add that you may want to move the entire setup forward approx 2-3 inches as if you are not using a body lift the valve covers and distributor will hit the firewall, especially if using an HEI distributor, Here is a pic of a BBC in a Burb using the stock small block mounts and location, as you can see its a tight fit, the other picture you can see the previous owners modifications to the fire wall to make it work, even so the distributor was almost touching.
