It really makes one think, just like in the "Open Plenum" offerings, the old "outdated" Holley 300-25 is still available NEW, and it still performs to this day, the price is right, the "Shape" is right, and is one of the least expensive intakes. It was still one of the nicest ports right out of the box. I have had and tested many, and even though it's old, it works and keeps up with the others OP's, especially in the 450-550HP range, with a 650DP, I have just as much, if not more bottom end than my dual plane setup, more mid range and the top end is just great. I had a new in box 300-36 and sold it, and installed it on a customers car, he loved everything about it, it performed as expected. If they ever made it again, I would buy one, and if I had the extra coin, the 69 Z/28 OEM one as well.
