1985 Buick Regal street/track

Since plans to build my mustang collapsed. I got rid of the car long story. Any way i bought a 85 regal and im wanting to get it into the low-mid 12sec range. I know im going to use a 350sb and i all ready have a 400 turbo tranny built. I dont know much about anything other than fords ive always had mustangs but i need to know what susspensions,supper chargers, and engine parts would work. So the car is fast but i also want a good car that handles corners. thanks for your help
