340 cam change

RLF...how is the low end torque with that crane cam and 2.94's....and what size rear tires? I have installed 2.94 rear gears in my new project but it will be some time before it's finished. After using 3.23, 3.55 and 3.91's i prefer the 3.23's but i'm thinking the 2.94's may be even better.
