I did a fitment test with the new pump and original pick up tube that came with the magnum and I also tried the old pump with original pick up tube it still hits the pan just barley right before all the bolt hole rails mate to the block. I also tried the new oil pump and old pick up tube off of a ‘72 LA block and it still hit . The difference between the original set up and the new oil pump set up is about .250”. I bought the oil pump about 3 years ago from rock auto. It’s a Melling pump . I have a picture of the pump but will post a picture of the block/ oil pump once I get home from work .
