Motor Swap?

I agree the 3800 supercharged engine would be a big improvement and it is almost plug n play. as that engine was used on the Regal (same body as yours) GS. If you go with the supercharged engine you want to get the transmission also...I also think the Regal had rear disc brakes and your Century had drums.....Ideally find a complete Regal GS and you should have all the parts you need to make your Century think it is a V8
