sb vs bb who cares it is horsepower and torque. I will tell you right now if you are under 50 years old, you will be used to "small" block power (375hp/375ft-lbs) in 6 months and want alot more. You also want torque at low rpm's do not get 500hp and 500ft-lbs of torque where the torque comes in at 4500rpms. You want torque at 2500rpms. I would recommend go with as much engine as you can afford and then stretch another 10%.
