Hello from an absolute newbie

I was driving down the road the other day and found a beautiful 68 valiant at a great price. It's a 318 with headers, dual exhaust, a couple MSD parts. Allegedly cammed, but having never driven a 318 I can't tell. There's clearly a vacuum leak so it's running a little wonky. I know nothing about mopar, looking forward to soaking up the info in the forum. Thanks in advance.
