Use a "High Flow" Brass Screen Filter & a Farpak Pan Gasket, I've seen many issues with aftermarket TH350 Felt Filters wadding up & clogging the pump intake.
OE SPX Filtran "Felt" TH350 filters are next to impossible to find, If you do.....I guarantee it will be over 25 years old.
Install a Magnet in the pan, GM# 29532686
This is what a high flow brass filter & a Farpak gasket looks like.
