yes they sure do have the hole, BUT the oil pump drive rotates in the opposite direction from the old 2.9L and 2.8L
This has been discussed so many times, especially on the old 2.9L forums
It CAN and HAS been done, but it is not easy or cheap.
Offenhouser made some performance intakes for the cologne V6 engines and the Cossworths overseas made wicked power ( can you say 350HP 2.9L) with these setups...good luck getting your hands on that stuff here...
