I have an original dual quad setup (from a 66 GT350 Shelby Mustang) on my HIPO 289. The engine is now in my Unique Cobra but is not yet finished. I ran the engine in a 65 mustang for many years and loved the performance from it. When I first got the setup it did not have the linkage, so I made my own and not knowing any better, connected both carbs to operate at the same time. The car always had a short lag in response (from too much fuel) and then came on like a rocket, when the vacuum secondaries opened it was like you mashed the throttle again. I originally thought that over 900 cfm was going to be way too much but other than the lag problem it worked fine. I now have the linkage set up right and am anxious to see how it runs now. My 289 had stock heads with 12-1 pistons, oversized valves and the Ford C7FE camshaft.
