My son wants to supercharge his 400 in his Dart. Myself I have never fooled with supercharged engines. So I was wandering as I figured about 9.0 comp is what we want to shoot for ? And do supercharged engines even worry about quench since I guess its tuffer to get with the lower comp ? He wants to use a blow through carb also. We will also have a custom cam made for it. Thanks for any help. Ron
