Were just in planning stage.
When saying gear right, the questions becomes what is right obviously people can gear however they choose. If were building a performance engine even if the goal is vague like a burn out throttle blimp machine you still want it to look perform in general distance and speed even in the street Eg... Idle or rolling start to 60-100 mph maybe more. Quarter or eight mile is easy it's there's a point where more gear won't help and the gearing needed for maximum 1/4 time will be different for a 318 and 360 and if both have similar hp curves you'll find torque to the ground is similar for both. You can gear however you want but it's not the fault or defect of the smaller engine if you didn't gear to take advantage of it. Which is why most should build the largest engine you can cause the gears people generally run 3.23-3.91 are gonna be more suited to it.
Generally when I say gear it right it would be with the max performance in the quarter mile in mind there has to be some common goal to compare from. I'm not saying people need/must gear for 1/4 mile but when comparing a 400 hp 318 to a 400 hp 440 both running 3.23 gears obviously the 318 is further away from running optimal gearing than the 440. The 318 would need around 38% more gear to be compromised the same so 4.46 4.30-4.56 would be the choices.
