Single plane vs dual plane intake

I agree. Trying to eek out every last ounce of power/torque that might be in an engine means that there are trade offs. Tire height, rear gears, vehicle weight, cubic inches, camshaft, compression ratio, intended use of the car, etc..... You have to look at the entire picture to make decisions that work in harmony with each other.

Doing that is a lifelong process and you find the end of the fun real quick. That's why I always say "pick one and go" when people ask for a cam recommendation and everybody is telling them the same thing within a few degrees and lift range. Once it gets narrowed down "that much" a dyno is the only tool that will tell the difference and we don't all have one of those in the back pocket. lol
