I was looking around for an rb30 block and stumbeled across this. They build these motors and sell them, it is a rb30 hybrid. Rb30E block(austrailian) and the rb26 head. They say this motor is making over 720hp on pump gas and is expected to make 900+ on race fuel, and they are expecting 8sec quarter at 160+mph with no nitrous. The cost is about 20k$ wich isnt that bad.
