Smallblock intake manifold shootout.

Intakes do different things to different combos, we know this.
If you have high flowing heads with an average dual plane, it's usually corked, and just from the un corking with a single plane that allows more air to the heads, can make more torque than the dual plane, and a load more of hp.

You can do a lot with a lil if you compensate=g stock 71 340 with their iron thermo intake cars for instance.
But we're not driving around g $tock drag car$

combo combo combo!

and what was their 1 combo they tested these on?

you don't know how it would run with a diff cam, or bigger headers, heads etc.

but I guess it's good as guide line?
