Yes I have. My engine is 540", 4.5" stroke. CR is 10.78 with MP Aluminum heads and solid street roller 248/254 @ .05. The car is heavy, 4,175lb with 3.54 gear. I liked the intake as it is dual plane with Vanke like plenum mods. It works very well on the street compared to the Stage V single plane I started with.
No one makes a progressive linkage, I run a solid that opens both carbs at once.
You will have to build your own fuel lines, I did mine out of stainless tubing, not easy.
Also, you will have to use an aftermarket air cleaner for the bore spacing and air horn size on the Hollys.
