I ran mine on a 440 with an 850 Holley and then a Proform 950. Did real well. Then I built a 500 stroker. In an attempt to keep everything under the Shaker, I modified the intake to accept a 1050 Dominator. I just screwed some aluminum bolts into the carb bolt holes and cut them off. Then opened the plenum up enough to clear the Dominator's throttle blades. Worked good on my street/strip Cuda. One of my favorite intakes.
