Like the low compression/ high vacuum engine benefiting from a performer, over a high compression working with a high rise open mnai. Both can shift quite a paradigm, with just single or dual plane manifolds. All those tests are around 10 hp/lbs apart. Not realistic to me.

It seemed that they were all so close in output, what would even be the advantage of one over the other, than aluminum weight savings and pure asthetics. The were all so close as to be almost negligable.

Ran 11.59 @ 117 with the Holley SD and ran 11.55 @ 116 with the RPM. It had more mph with the single plane SD but it 60 ft better with the RPM enough to et a tad faster with less mph. He left the RPM on as he said it feels better on the low end street driving with the RPM. He has since ported his heads and run 11.45 @ 117 with the RPM.

If the results are close, it does show on a stockish 383 that the manifold isn't the bottleneck. On part 2 where they bolt on the cnc ported aftermarket heads, the results do change a good bit. Even then, it's not an extreme, rpm screamer of a build.
