He is currently doing mine. Had to send him my sump, oil pick-up arm, and oil pump housing. The capacity is increased to 7ltrs, the oil pick-up is relocated to ensure optimum position and is surrounded by baffles, the oil pump is modified to suck oil from the right hand side (by removing the welsh plug and inserting a fitting). I will need to block off the factory oil intake, to the pump, in the block.
His manifolds are said to be top notch too
