New Engine for my Barracuda

I just finished a nicely built Mopar 318 for my 66 Barracuda. I've been waiting over 6 years to get this car on the road again so I'm pretty excited about it. It's down at the shop (B&T Custom in Sparks, NV) getting the engine installed. They are also putting in a set of TTI headers (installation of which requires disassembly of the front suspension - something beyond my mechanical skills) and converting the car from a 3 speed auto to a 5 speed manual transmission. I'm really anxious to drive this. The 318 should have a ton more power than the 273 it's replacing but still get OK gas mileage. It should be great for trips to visit my parents in Bishop, California.
