Yeah I thought I made a score when I picked up the pan for $400 and then found a brand new pump for $600. I was so excited until I noticed the one wouldn't bolt to the other. Called Dailey, they said they weren't compatible, the pan was off a Daytona Prototype, used a small pump. The pump was Nascar stuff, which used a big pump. It was physically to large, and would hit the block . He suggested I ditch them, and buy a new system.
You know I couldn't do that. Luckily my buddy Scott is a pretty good machinist, and a big car guy. So I built an adapter, the bad part was, it had to be shaped like a wedge so the big pump would be canted away from the block. Pump had round ports, pan had square. Bill Dailey said it couldn't be done, "challenge excepted". It was a PITA. What Bill probably meant was, no one in their right mind would go through that much trouble, just buy a new system. It would have broke my heart for those two phenomenal parts to be setting on a shelf, collecting dust. At least this way they get used, and I have a Dailey system with a new pump for about a grand.
