i had a carquest B49 filter on it but we changed that to a racing filter didnt seem to change much.i dont know what pump is in it the motor was in the car when i bought it.i do know that it only has 13 nights on the motor since new rod and main bearings were put in.it was fine before we changed the oil.that is what puzzles me.it didnt seem to matter really whether it was in corner or on straight i do know that the pressure still dropped under acceleration.i was told to put extra oil in it andseemed to level it out alittle better,but then was told that it would blow the seals.
