I did an SOHC intake comparo years ago, and that intake out-performed the factory 2X4 dual plane from 5500 on up.  I also had a Munro 2X4 intake, which was better than either of them between 5500 and 6500.  The single 4 intakes were down significantly on power, but I got one from John Vermeersch that had been converted to a Dominator flange, and that one was 50 HP better than the other single 4 manifolds.

Sorry but that info is not available at the moment.  The computer where it is stored is on the fritz, and I haven't gotten it fixed yet...

It is highly unlikely to find one at all, let alone reasonably priced. They are very difficult to find and quite pricey. It's the only cast single plane intake that will fit under a hood. EVERYONE wants one...
