Well because a Hemi needs to be spun over 8000rpm and I doubt a 5 quart pan has enough capacity. Also the 62-65 K member is different than the later model units which brings us back to the fact that Toms K member is going to have to be notched so the oil pan will fit therefore he should just get the larger capacity unit and done with it. This is assuming his car has the early K member still installed. It cost at least 20k to build one of these engines and I sure would not recommend he use a stock type 4-5 quart pan.
Tom, Please let us know what you end up using.
