Better intake LD4B or Street Dominator?

yeah that is true. Holley did spend much $ designing a new intake. If you look at all the V8 intakes they made, all had different layouts.

I think either intake you be happy with, the dual plane your wife might give prefer due to the better off idle response. In a high stall, 4.10 car flat out, the holley would come out on top, IOM

What carb are you going to use--if holley use the holley intake, if Carter / eddy use the eddy
