Single plane vs dual plane intake

I agree when you compare a 4 inch arm stroker to a stock stroke whatever CID you want.

Disagree on single vs dual plane on the same stroker. But there is plenty of torque for low speed driving. There should be no issue really.

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.
