Oh, come on. :colors:
And out of the three you chose to stay with the Chinese intake? Really?
Dug up a couple of photos of my Magnum intake comparisons to the Chinese. Not the best, but you'll get the idea. Hopefully I'll dig up the other ones.

Maybe its just me, but one of these looks like something a jr high shop class put together. Check out how the ports on this intake aren't symmetrical left to right, or top to bottom. They're not even the same size. WOW. You don't often see "core shift" make one port 1/8" taller than another.
On the left hand port look how steep the ramp is. On the right, check out how far the side of the port intrudes into the air path vs. the edelbrock.
