The pro comp 140 pump is the exact same as the Holley black. I had a leaky gasket on my Pro comp and put a Holley kit in it. It worked fine it was just dripping a little out of the plate on the bottom so I put a kit in it. I think this pump was $40 off ebay. I just cant believe it still works. I was running a 440 that ran low 12's in a 4000 lb ram and sprayed it 150 nitrous and pump stilled kept up.
