Fast ETs Using a Dual plane ( BB & SB )
Is it worth cutting out the divider on an aftermarket dual plane? With my stock 68-69 340 intake, absolutely. But a well scienced out aftermarket one? I know that a stock 340 intake with the divider cut down and massaged as much as possible got this car to mid 10’s. I just don’t think the intakes are the bottleneck in a small block. Cylinder head flow is, at least until you are out of production castings.
