Smallblock intake manifold shootout.

Unless somebody beat me to it and I missed it.....Lookie what I found!

One thing to note in the story is that the Torker II was modified. I don't know why that was even included since it was not an apples-to-apples comparison with the other "stock" manifolds.

One also has to factor in jetteing. It is not uncommon to find that an intake swap requires the carb to be "re-optimized" if you really want to see everything it has to offer - jetting, squirters, pump cams, etc. A dual plane will have a different vacuum signal than a single plane. Different intakes of the same design can also affect the signal due to plenum height, runner volume, length, etc. A spacer, different headers, opening the exhaust, removing an air cleaner, etc. can also affect a carb set-up.

I did a back-to-back comparison between a Weiand Stealth and a Holley Strip Dominator a couple of years ago. I ran both for years, just didn't compare them on the same weekend. I had to stagger-jet the Weiand dual plane for best results. It was almost as good as the Holley single plane but the Holley appeared to be a bit better for my particular combo by almost .10 and 1+ mph. I wish I had more time to do more tuning on both, but settled on the Holley. I figure with all the cam duration, gear, converter stall/flash, etc. that I run, the higher operating range of the Holley worked better because the torque range and peak of the Stealth was skipped over by my 5,000 rpm converter flash, and the rpm's stay above that through the run. I also figure that any milder combos would find the Stealth or similar dual plane as good or better. Just my experience and 2 cents worth.
