Daily Driver Engine 318 vs 360, what one?

Whats going to be the better engine for daily driver duty? Conditions around 425 hp and MPGs. (not expecting to get 30mpg, but better than 10mpg)
I'll be thinking out loud hear.

I was just thinking what engine would be better. Getting 425 hp out of a 318 can be done but, how much will drivability suffer? Since the 360 weights about 25lbs more the 360 would need to produce about 450 hp for the same power to weight ratio.

This is what I was thinking so far:

318 Pros
Smaller displacement would have a better chance at getting decent MPGs. Lighter, less weight on the front of the car. Cheaper.
318 Cons
"Hotter" cam, more of a choppy idle. More difficult to achieve horsepower goal. Power in the high RPM band, less low end torque.

360 Pros
Bigger displacement easier to achieve 450 hp. Less choppy idle. Low end torque, won't need REV it as high.
360 Cons
Weight, bigger displacement, use more fuel.


A 360 should produce more low end torque making it more fun to drive around. Am I on the right track, does anyone else agree with my train of thought hear?

What would you do/ opinion?
