426 Hemi

Hemi's got the "cool" factor. They look cool no matter what you put them in.

But 440's are the street engine. Cheaper to build. Power out the ***. Roast tires at will. Stuff it into an A body and hold on. And lets not forget how cool the 440 6-pack looks. Personally I'm a 440 fan. Favourite car is a 69 1/2 road runner 440 six pack.
