Why not put on some thicker head gaskets and put your 177 blowers on your 540's. That would make a real hot 525sc. Not being a dic#. I love my 525sc's. Always wonder how they would be as 540's

what's bottom line on your 540's? also are you looking for 525SC's complete? i have 2, 525 blowers - intakes that were take offs with very low hours. valako can verify that.

177s On 540s Would Do Nothing But Create Heat, Go Bigger 871,or Bigger And Make Them Run
