Any recommendations for building a '73 340?

Wait until Autozone has a 20% coupon. I was able to get a pair of new D453 ceramic coated Doug's headers for $475 shipping to my door back in January. They also had free shipping on orders over $100.

I remember when you got those. That was a killer deal. It almost made me buy a set and I didn't even have an early A body at the time. lol
