New to drag racing. Need advice.

I bought a 69 dart late this summer. It wasn't running at the time. Anyway, it's an older drag racing build. I'm trying to squeeze the most out of it that I can. Honestly....I don't know where to start.

I got the car running just in time to make the last local 300 foot drag. Check out below.....start the video at 30 seconds if you want to get straight to the action.
