You're right about the Summit pricing on Summit branding. Funny thing you brought that up. Summit Racing was a Mom and Pop thing when I was growing up about 40 miles west from where I grew up In Youngstown, Ohio. We used to make the drive all the time for our weekend projects when I was in High school. What's changed is, since they started advertising in every Hot Rod and Car Craft magazine in the 80's, they're in a position to have parts made for them by the same companies they represent. In other words, melling will sell them an oil pump or Milodon will sell them an oil pan for a HUGE discount becuase they don't have to stand behind it, for one, and they can mass produce anything. Summit Has to assume the warranty, and the mfr is out of it. Same part, but where you used to buy a Holley Fuel pump, and it was replaced if failed, no questions asked, the same pump made by holley, under the Summit name, well different story.
