Well, I fired up my 454 for the second time this weekend after I finished the swap. The first time I only started it up and let it run for a little bit since I hadn't hooked up the exhaust up. Saturday I pulled it out of the garage and I let it run for a good while, BUT i noticed that my PS is not working. So I was just wondering if anyone has any ideas. Here's the setup, one used big block pump bought on ebay, original small block lines, plenty of PS fluid, I over-filled it actually. It appears the SB lines are longer and end up looking like two snakes going at it. So I wonder if the lines are restricting flow and not running the box. Or if simply need a new pump. Any thoughts?? Thanks!!
