Mean416 said I love it when people are like, "you need torque of a big block" HP is just a calculation. You gotta make a bunch of torque to get to 700 HP, big block or small block. A Big block will make more low end torque by virtue of displacement but for mud racing your gonna be revving. I think that guys should either make a recommendation for 700hp or just admit they don't know. Click to expand...
