All I can say is WOW. Are you determined and highly skilled !!!
To answer your question on the cam you'd need to look into the total package, compression ratio, head flow rate, axle gear ratio, rear tire diameter, stall converter? etc, all the parts need to work together. If you can post your total set up someone over here in the US can contact comp cams or which ever cam outfit you'd like and ask them for a recommendation - There are many many choices when you start looking at cams.
