Fast ETs Using a Dual plane ( BB & SB )

Is it worth cutting out the divider on an aftermarket dual plane?

IDK for sure but a spacer seems to normally do well.

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.

I’ve been saying this for years only to have much of the forum throw it back at me as wrong or only for mild mild cams. I won’t argue that an aftermarket intake will be better but I will still state “For on the cheap a factory intake can’t be beat.” Then when you start massaging them… Ha ha ha ha ha ….

I love the stock intake and TQ…. Yea… unable to perform… riiiiight….
