1966 charger

I have a 66 charger with a 361 and 727 trans. i bought it to restore and have fun with. I recently ordered some performance parts to go with the rebuild, performance cam, lifters, double roller timing chain, and headers. I also had the trans beefed up a bit. Am I wasting my time trying to build this motor for good performance? Ive heard its a boat anchor.

Thanks,
Tony
