Technical flathead parts article

Any of you guys see that article a few months ago comparing Edelbrock, Offy, Winfield, and maybe even Wieand manifolds?
I know I had it, but can't find it now.
Does anyone know which magazine and issue it was in?
Thanks in advance...whith this group, I'd figure to see an answer in 3...2...1...

 

The mag was Hotrod they did dyno runs comparing the different brands of intakes including multi carb to single four barrel pretty interesting stuff

 

I believe it was Jan or Feb 2013 Hot Rod. Do a google search for flathead intake test+Hot Rod Magazine. Good luck.

 

Hot Rod 01/13. Based on that test I choose Edelbrock Slingshot 2X2.

Thanks a bunch guys, nobody does it better than here!

 

Does the slingshot 2 x 2 come in a 49-53 version? The only ones I've seen are up through 48.

 

They only list the #1103 32-48 on their website.
