          Cavitation will be your problem if high rpm is maintained for more than a few seconds.
          You need a dry sump or an accusump.

                  am still on hydraulic lifters at the mo, but thinking of going over to solid at a later date!

                  just need to get it running and driving at the mo, taking up room in the workshop and customers cars to get done!
