Buddy of mine has Bo Laws Holley on his car and loves it. He bought it maybe 8-10 years ago. There's also Thumper (IIRC) on this board, though I haven't seen a post from him in some time. I've never heard anything but praise for his carbs.
My Gary Williams carbs always ran great out of the box. I have had 4 or 5 of them over the years and have 2 of them now.
