I talked with the Holley guys at LS Fest and he said they are ready to ship. You have to make the order then they will get the correct top for your order paired with the base. He said everything has been a go for a while. The goofy shipping dates on Summit's website is scaring people away.

I have gone 10.04@ 133.35 with the Holley TR and 2 660 carbs,this equates to about 50 more than my single carb setup. The motor made around 650hp on Joe Shermans dyno with the single carb and GM PP intake. I did have a cam ground for the TR at the same time so its the result of both mods. Im happy with it overall and there is more left in it.
