Mopar Magnum

Hey guys, I'm new to this forum and I have a 1967 barracuda handed down to me from my grandfather. Right now it has a Mopar Magnum 360 in it and I am curious as to what thoughts you guys have in regards to this engine. Is it worth building up? heads etc, or would it be better to swap to something else. This is the car as it is right now and it's engine. I have upgraded it to power disc brakes in the front but this is a pic before we put the booster in.

Woohoo! Is that the way the car looked when your grandfather owned it?
