Streetmaster to Airgap

I guess it’s one of those things where people interpret the same info in different ways.

I read the article.......
One interpretation is that the modern AG intake was hardly any different than the old tiny SM on a 340.

My take away was.......if you take a 340, that has stock 1.88 heads on it, a small cam, a small carb, and stock log manifolds from a 318 on it along with the SM manifold...... and only upgrade the restriction that is the SM manifold....... you don’t see a big change in power.
Frankly....... no surprise there for me.

Seeing as how it was the first item they changed, I took that as a sign that they felt it needed to be swapped to not hold back the power that subsequent part changes could yield.
