I think the Edelbrock LD4B and the Weiand Stealth are the same thing...
yeah, its the angle of the photo. I have the stealth a little too low in the shot, so they aren't exactly parallel. Also, the raised carb pad on the stealth plays all kinds of tricks on your eyes.
I think the Edelbrock LD4B script makes that runner look larger than it is. I measured that one in particular, and they're so close its pretty unbelievable. Interestingly to me, the driver's side front runners on the Stealth look bigger than the LD4B in these photos, but they're not.
It doesn't help that I don't have all the fittings stripped off of there either.
