Another 318 set up

It depends on the type of performance and the level you desire.

The level of performance is an HP issue, you need a certain amount of HP to accomplish what ever your after.

Both horsepower and torque need to be taken into consideration along with the power curve. Remember, a lot of us have street cars with 3 speed slush-o-matics and a highway rear gear, so an high rpm race engine is not fit for that use.

The augment cannot be one sided, dan is not going to be rotating the earth with his imaginary 318 build, I don't think that was his intention.

How you get that HP is a design issue, you got to figure out best rpm range gears etc.. And how much torque is needed at those rpms to make the hp to accomplish what ever performance goals you have.

Eg.. Say you are towing heavy loads in mountainous areas and figure you need about 400 hp to accomplish your goals at general road speeds, you could gear an higher rpm engine to do it like a rock crawler or just build the 400 hp at your average rpm you drive at say 2000 rpm so the power is just a throttle press away, So the torque needed to do that is 1050 lbs-ft, then you would need to figure out how much displacement would be needed etc.. probably use diesel and a power adder to cut the displacement down some.
