This is a classic example of why one intake doesn't fit all. Just for giggles and grins, I looked on Edelbrock's online catalog and saw that they offer 14 different dual plane intakes for the SBC. 14 different dual planes, how can there be that much difference in one manifold that you have to make 14 different versions of it to accomodate the demand....again, one intake doesn't fit all needs. They have exactly 50 different intakes total for the SBC. So there is plenty of room to make and offer something for most everyone's needs with the inlines, so maybe before long there will be 14 intakes for the 250/292's.
