I am building a 400 small block two bolt main. the block is bored .30 and i am using vortec heads. I need the pistons at about 9:1, but i want to build the engine where it is quick out of the hole. any suggest on pistons crank cam would be very helpful. I was to run regular gas not racing gas. But I want the torque power out of the hole. engine is going in a 1970 c-10 pickup 2wd with 3:73 gear.
