Yep. Install the pump onto the rear main cap. Now insert the pick up loosely so that you can take a measurement. When the motor is inverted and horizontal, measure the distance from the oil pan rails on the block, to the bottom of the pick up/highest point. Now measure the distance on the oil pan from the mounting flange to the deepest part. You should have 3/8s of an inch clerance. Adjust the pick-up accordingly and shove it in to secure it.

Next, secure the pump in a vice and take a 5/8s open end wrench and place it over the buldge of the pick-up and tap it in with a hammer.

Next, find a piece of metal which you can mount to one of the bolts of the pump and weld the other end unto the pick-up pipe. This last step is just for insurance purposes. I speak from bad experiences
