Gee i wish it was that easy put a monster motor in and it will put me into 11's funny the calculators put me into 10's but it does't get there. theres a bit more to it than that, like suspension and driveline, traction. before you build a motor you need to set your goals on what you want achieve i like option B obviously 500hp is easy and streetable. standard 351W blocks good up to 700ish hp if you want to spin faster than 6500 you need to go to an aftermarket block with cleveland sized mains big heads etc and it will all be getting a bit radical. then you can forget all the standard running gear the torque will kill it, sell the toploader while its still in one piece. cheap horsepower is a myth.
